GENERAL INFORMATION
1.1 Specifications
This manual covers the operation and maintenance of the Cushman Model CE-3 FM Communications
Monitor. Specifications are given in Table 1-1.
1.2 Function
The Cushman CE-3 FM Communications Monitor is designed to check the frequency and FM deviation of
transmitters operating in the FM communication bands. It can also generate FM and CW signals within those
bands. The output level of the generated signal is adjustable over a calibrated range of 0.1 to 100 microvolts.
This feature is useful in checking the sensitivity of FM communication receivers.
Frequencies in the range of 1 kHz to 40 MHz and beyond can be generated fOT receiver LF. test and other
purposes. With the use of the Cushman Model 308 Decade Frequency Divider plug-in in conjunction with the CE-3
Monitor, frequencies from 0.1 Hz to 4 kHz are available in O.l-Hz increments. Further, starting 'it 4 kHz,
frequency increments of 1 Hz are available up to 40 kHz. From 40 kHz to 400 kHz the increments are in 10-Hz
steps. This allows testing of tone-operated squelch circuits in receivers so equipped.

1.3 General Description
The CE-3 (Figure 1-1) is basically a highly specialized VHF/UHF superheterodyne receiver. The required
local-oscillator (LO) frequency, derived from a highly stable crystal oscillator, is automatically offset 10 MHz
from the "dialed-in" frequency. When the incoming signal at the dialed-in frequency is of sufficient amplitude,
the squelch circuit activates the frequency error detector and discriminator circuits, and allows the frequency
error meter and the deviation-measuring plug-in (meter or oscilloscope) to operate.
The incoming signal is fed into a broad-band mixer or preselector (depending on choice of plug-ins), from
either the telescoping antenna supplied with the Monitor or from an outdoor antenna, and a 10-M.Hz LF. voltage
is generated. This 10-MHz signal is amplified and mixed with 9.9 MHz to create a second LF. of 100 kHz, which
is further amplified and fed into a special 100-kHz discriminator.
The discriminator output operates the FREQUENCY meter, which indicates any frequency error between the
dialed-in channel and the signal being measured. Simultaneously, a peak-reading circuit drives either the Model
302 FM Deviation Meter or the Model 301 Oscilloscope, whichever is plugged in, to indicate any FM deviation
of the incoming signal. When the Model 302 is being used, the DEVIATION PEAKS lamp on its front panel flashes
instantaneously when the absolute peak excursions of modulation exceed a preset amount. A scope jack on the
Model 302 plug-in provides for visual observation of the incoming modulati.on waveform, and a receptacle on the
back of the CE-3 makes it possible to connect Model 309 Remote Meters so that frequency error and FM devi
ation can be read at a distance of up to several hundred feet from the Monitor.
Signal generation of the dialed-in frequency is accomplished by mixing the LO signal with a 10-MHz signal,
which may be either CW or FM. The amplitude of the generated signal is controlled by the SIGNAL GEN. ATTEN.
to provide a directly calibrated output of 0.1 to 100 microvolts through a fixed 20-db pad furnished with the
instrument. The output level will be nominally 10 times greater if the pad is not used. It is emphasized, how
ever, that the pad should be used at all times. A 1/32-ampere fuse in the 20-db pad protects the pad and the in
put circuit of the CE-3 against accidental keying of a transmitter.
When the 10-MHz signal used to generate the dialed-in frequency is frequency-modulated, with either the
I-kHz internal oscillator or external tones, the SIG. GEN. output is frequency-modulated by the same amount.
The amount of modulation is indicated directly on the FM deviation meter or oscilloscope.
LF. and audio frequencies in two ranges (1 kHz to 4 MHz and 4 to 40 MHz) are generated by the Frequency
Synthesizer and are selected by a range switch and the same frequency control knobs that are used to dial in a
transmitter frequency.
The numbers indicating the dialed-in frequency are lighted for easy reading. If a frequency not covered by
the CE-3 is accidentally dialed in, the lighted numbers flash on and off to indicate that the selected channel can
not be monitored or generated by the CE-3.

All dc voltages are regulated and negative feedback is used in circuitry where stability is essential. The
crystal oscillator accuracy may be checked against WWV at any time and is easily reset if it should be neces
sary. See Section 5 for specific information.
A detailed circuit description is given in Section 4.
1.4 Accessories
Three types of accessories are available for use with the CE-3: units which plug into the Monitor's front
panel, instruments external to the Monitor itself, and items furnished with the Monitor but not integral parts
of it.
1.4.1 Plug-In Units. A receptacle on the left side of the Monitor front panel accepts either the Model 301
Oscilloscope or the Model 302 FM Deviation Meter. One or the othei' of these must be used to provide FM
deviation measurements. The right-hand front-panel receptacle accepts the Model 303 Broadband Mixer, one
of three RF Preselectors (Models 304, 305, and 306), the Model 308 Decade Frequency Divider, or the Model
310 Frequency Converter. The Broadband Mixer and Frequency Converter are used for measuring frequency
and FM deviation of local transmitters; the preselectors are used to monitor transmitters up to 50 miles distant;
and the Model 308 Decade Frequency Divider provides submultiples of the LF. FREQUENCIES output of the CE-3
for testing tone-operated squelch circuits. Each of these plug-in units is described below.
Model 301 Oscilloscope. This plug-in scope allows a visual examination of the exact modulation delivered
by the transmitter. Unbalanced modulation, pulses from the power supply, unusual clipping, and other problems
are instantaneously detected so that appropriate repairs can be made. The Model 301 has an automatic sync
circuit, similar to that found in the most advanced laboratory instruments, to lock on and precisely display wave
Iorms. Vertical display is directly calibrated to show deviation on anyone of three ranges: ±1.5, ±5, and ±15 kHz.
Switches on the front of the scope panel allow connection of external signals to the vertical input while using the
internal sweep. External signals may also be connected to the horizontal input. This allows use of the scope
independently of the monitoring function for routine testing, troubleshooting', displaying Lissajous patterns, etc.
The Oscilloscope can also be used for receiver LF. bandwidth and discriminator alignment, as described in the
Model 301 manual.
Model 302 FM Deviation Meter. The Deviation Meter prOVides three directly calibrated ranges: 0-2.5, 0-6,
and 0-25 kHz. An instantaneous peak indicator light flashes when the absolute peak deviation of the incoming
carrier exceeds a preset amount determined by the operator. Operation and accuracy of the flasher are not
affected by modulation frequency, repetition rate, or waveform. The deviation level at which the peak indicator
flashes is adjustable by the front-panel SET control. A switch allows selection and measurement of either + or
- deviation peaks. There is also a scope jack on the meter plug-in for simultaneous meter and scope observa
tions of deviation.
Model 303 Broad-Band Mixer. The Broad-Band Mixer operates over all three bands covered by the CE-3.
Sensitivity is less than 10 millivolts, for close-in monitoring and in-shop measurements. A crystal filter in the
Braod-Band Mixer provides sharp selectivity in areas where many strong RF signals are present. This filter
is actuated by a front-panel toggle switch.
RF Preselectors. Three different plug-in RF preselectors are available for use in the CE-3, one for each
of the commonly used bands. Model 304 covers the range from 25 to 50 MHz, Model 305 covers 145 to 175 MHz,
and Model 306 covers 450 to 512 MHz. The sensitivity of these preselectors - on the order of 20 microvolts
makes it possible to monitor base stations up to 50 miles away or to accurately identify the exact source of any
interference encountered. The preselectors also have the same crystal filter feature as the Broad-Band Mixer,
for sharp selectivity.
1-5
Model 308 Decade Frequency Divider. The Decade Frequency Divider plug-in divides the frequency of the
1. F. signal generated by the CE-3 so that the signal can be used to test tone selective circuits and similar
devices used in receivers. Frequency division ratios of 10, 100, and 1000 can be selected by a switch on the
front panel of the plug-in unit. The input signal for the 308 is normally obtained from the CE-3 through a mating
plug on the back of the Divider plug-in; in addition, frequencies up to 10 MHz from other sources can be divided
by applying them through a BNC COlU1ector on the front panel of the Model 308.
Model 310 Frequency Converter. The Model 310 Frequency Converter provides coverage of an additional
band - 400 to 420 MHz. The complete frequency coverage when using a Model 310 with the CE-3 is:
20 - 80 MHz
120 - 180 MHz
400 - 420 MHz
450 - 512 MHz
910 - 1010 MHz (using harmonics).
The Model 310 converts frequencies in the 400-420 MHz band to the 40-60 MHz portion of the 20-80 MHz
band.
1.4.2 Externa~ Instruments. Two accessory instruments - the Model 107 Deviation Calibrator and the Model
309 Remote Meters - can be connected to the CE -3 by cables.
Model 107 FM Deviation Calibrator. The Model 107 provides a means of checking the deviation calibration
of the Model 301 Oscilloscope and the Model 302 FM Deviation Meter on each of their FM deviation ranges. The
calibrator connects to the CE -3 by means of a cable which plugs into a receptacle on the side of the Monitor.
Model 309 Remote Meters. The Model 309 consists of an FM DEVIATION meter and a FREQUENCY meter
mounted in a box which can be located at a distance of up to several hundred feet from the C E-3. The cable
from the Remote Meters plugs into the accessory receptacle on the back of the CE-3. A switch near the
receptacle selects either internal or remote meters.
1.4.3 Other Accessory Items. Two accessory items are supplied with the instrument - a telescoping antenna
for picking up transmitter signals and a 20-db pad with cable for use with the CE-3 when a generated signal is
being fed into a receiver. Both the pad and cable are stored inside the front cover of the instrument. Installation
of the antenna is covered in Section 3.3, and use of the 20-db pad is described in Section 5.2.5.

SECTION 2
INSTALLATION
2.1 Unpacking and Inspection
No special instructions are required for unpacking the Model CE -3 FM Communications Monitor other than
to inspect the packing box and the instrument for signs of possible shipping damage. Check performance as
outlined in the Operating Instructions (Section 3). If the instrument is damaged or fails to operate properly,
file a claim with the transportation agency or, if insured separately, with the insurance company. It is recom
mended that the.-shipping box and foam packaging be kept for possible use at a later date.
2.2 Environmental Requirements
2.2.1 Temperature. The CE -3 is designed to operate at ambient temperatures between + 100 F and + 1300 F.
Care must be used to avoid exceeding these temperatures in the field. For instance, the internal temperature
of a closed automobile trunk may exceed 1500 F during summer daylight hours. Also, leaving an instrument
outside in bright sunlight on a hot day may raisl? the internal temperature beyond its ratings. Avoid blocking
the cabinet ventilating louvers. These louvers are provided to prevent excessive internal temperature rise.
Exceeding the upper or lower temperature limits (within reason) should not result in damage to the instrument.
However, it may cause poor performance or actual malfunctioning.
2.2.2 RF Fields. In locations where extremely high radiation fields exist (such as when an antenna is connected
directly to a transmitter which is physically near the CE-3), it is recommended that the telescoping antenna be
pushed down to reduce the pickup. In locations where many high-power transmitters are in use, interference may
be experienced if the transmitters are operating within 90 kHz of each other. In such cases, the SELECTIVITY
switch on the Model 303 Broadband Mixer should be placed in the SHARP position. If the interference still pre
vents satisfactory measurements, it may be advisable to use an RF attenuator aud cable for direct connection
between the transmitter to be monitored and the CE-3. Contact Cushman Electronics for further information.
2.3 Power Requirements
The CE-3 operates from a 117-volt or 230-volt (± 10%) ac source, 50 to 400 Hz. Power consumption is
75 watts.
2.4 Warm-Up Requirements
The frequency accuracy of the CE-3 depends on maintaining the master-oscillator crystal at a constant
temperature. This temperature is held constanl by a thermostatically controlled oven. Therefore, it is
important that the instrument be plugged into its ac source for at least 15 minutes prior to use. * The oven
operation is independent of the settinl' of any panel control. It is recommended that the instrument be installed
in a location where it can be kept plugged into its power source. This keeps the oven at its constant operating
temperature so that the instrument is ready to make precise measurements within seconds after the combination
SPEAKER VOLUME control-on/off switch is rotated to turn the instrument on.
* If the instrument has been stored al a temperature below +32 0 F, additional warm-up time may be required.

SECTION 3
OPERATING INSTRUCTIONS
3.1 General
The Model CE-3 can be operated in any of the fGlllowing modes:
a. Frequency and Deviation Measurement. The incoming signal is applied through the front-panel ANT.
connector, either through a coaxial cable from an outside antenna or from the telescoping antenna which connects
to the ANT. connector. The signal 'frequency is measured by "dialing in" the assigned frequency of the trans
mitter by means of the six frequency selector switches; any frequency error will be indicated by the FREQUENCY
meter. Deviation will be indicated simultaneously by the FM DEVIATION meter on the Deviation Meter plug-in
or by the Oscilloscope plug~in, whichever is plugged in. An instantaneous peak indicator light on the Deviation
Meter plug-in flashes when the absolute peak deviation of the incoming carrier exceeds a preset amount.
Operation and accuracy of the flasher are not affected by modulating frequency, repetition rate, or waveform.
A built-in speaker provides continous aural monitoring of modulation on the incoming carrier.
b. RF Signal Generation. A desired channel is generated by dialing in that frequency by means of the six
frequency selector knobs. The generated signal (CW or FM) is available at the SIGNAL GEN. OUT connector.
A precision attenuator provides directly calibrated outputs of 0-1, 1-10, and 10-100 microvolts. The output can
be frequency-modulated with continuously variable deviation from zero to 25 kHz. The amount of deviation is
read directly on the FM DEVIATION meter or on the Oscilloscope. A I-kHz internal modulating frequency is
provided; external modulation can also be used.
c. I.F. and Audio Signal Generation. When the I.F. FREQUENCIES selector switch is in the 0-4 MHz
position, output frequencies from 1 kHz to 3.9999 MHz can be generated in 100-Hz increments. In the 4-40 MHz
position of the switch, frequencies will be generated on a harmonic basis in I-kHz increments. The generated
signal is available at the I.F. FREQUENCIES OUTPUT connector, and the level is continuously adjustable by
means of the adjacent I.F. LEVE L control.
3.2 Front-Panel Controls
The front-panel controls, displays, and connectors are listed in Table 3-1 in a top-to-bottom order, and
are illustrated in Figure 3-1. The black control knob below the FREQUENCY meter, which is used to switch
from the signal-measurement function to the signal-generation function, is called the "function switch" in the
table and throughout the text. The six knobs in a row just below the frequency display window are used to
"dial-in" a frequency; they are referred to as the "frequency selector switches." Table 3-1 also describes the
connectors for auxiliary equipment, located on the side and back panels. Operating controls for the plug-in
units are described in the instruction books for those units.
3.3 Turn-On and Warm-Up
a. Plug the power cord into. an ac power outlet (115 volts, 50 to 400 HZ) and turn on the power by means of
the on/off switch on the SPEAKER VOLUME control.
b. Allow the CE-3 to warm up for approximately 15 minutes.*
* If the instrument has been stored at a temperature below +32 0 F, additional warm-up time may be required.

Function
Indicates received signal frequency error. The amount of frequency error, and whether it is high or low with respect to the frequency set up on the digital indicator display, is directly indicated in kHz. The lever switch below the meter selects the full-scale FREQUENCY meter range.
The meter is also used to monitor the center frequency of the signal generator output when the internal FM modulator is being used. The meter is automatically switched to the ± 5-kHz rang'e when the function switch is in the FM position.
Turns on when a received signal is strong enough for reliable measurements. The light will always be on when the function switch is in the CAL, CW, OR FM position. It will turn on in the FREQ.-DEV. MEASURE position when the received signal is strong enough to cause fuB I.F. limiting.
This position is used for zeroing the FREQUENCY meter by means of the inner red control knob. When the function switch is in the CAL. position, the FREQUENCY meter range is automatically switched to ± 1.5 kHz regardless of the position of the range switch.
In this position the CE-3 is a receiver-monitor, and will measure both carrier frequency and FM deviation of an incoming signal.
In this position, the CE-3 is a signal generator. The output signal is unmodulated, and directly calibrated in microvolts.
In this position, the CE-3 is an FM signal generator. The output signal is directly calibrated in microvolts. The frequency of the generated signal is monitored by the FREQUENCY meter, and the FM deviation is monitored by the Oscilloscope or Deviation Meter plug-in.
Indicates cycling of the crystal oven. The oven will normally cycle on for approximately 5 seconds and off for approximately 30 seconds after it has reached its operating temperature.
When on, this Ught indicates an unlocked condition in the Frequency Synthesizer of the CE-3.
The control knobs directly below the frequency display window are for dialing-in the desired frequency. The frequency display is wired so that the window lights will flash on and off if a frequency not covered by the CE-3 is accidentally dialed in. When this happens, the UNLOCKED light will normally come on. By watching the flashing display, the digit which has been incorrectly dialed-in can be determined.

These lights indicate the units in which the frequency is being displayed. For all operations described in this book, only the MHz light will be on. However, when a Model 308 Decade Frequency Divider is used with the CE-3 to divide the audio output frequencies from the I.F. generator, the decimal point and frequency indicator lights will shift to indicate the actual output from the Decade Frequency Divider.
I.F. signals can be generated by turning the left frequency selector switch to its I.F. position. Then, with the I.F. FREQUENCIES range switch set to 0-4 MHz, frequencies between 1 kHz and 4 MHz can be dialed-in on the frequency selector switches. When the I.F. FREQUENCIES range switch is in the 4-40 MHz position, frequencies between 4 and 40 MHz can be generated on a harmonic basis. For both ranges, the signal appears at the I.F. FREQUENCIES OUTPUT connector, and its level can be adjusted by the I.F. LEVEL control.
In the OFF position, removes ac power from all units of the instrument except the crystal oven. In other positions, supplies ac power to the instrument and provides a means for adjusting the speaker output level.
When the function switch is in the FM position, the FM MOD. switch selects the input to the modulator. In the EXT. position, the switch connects the modulator input to the ENC connector just below the switch to allow use of external tones. in the INT. position, an internal I-kHz oscillator is turned on to frequency-modulate the frequency generator. The same I-kHz signal is available at the ENC connector for use in modulating a transmitter or repeater.
These two controls are used when the function switch is in the FM position.
The DEV. ADJ. control sets the desired amowlt of deviation of the FM signal generator output. The deviation is monitored on the Deviation Meter or Oscilloscope plug-in. The DEV. ADJ. control also adjusts the level of the internally generated I-kHz signal at the 1 kHz OUT connector.
The FM CAL. control is used to adjust the center frequency of the generated FM signal, as indicated on the FREQUENCY meter. The meter range is automatically ± 5 kHz when the function switch is in the FM position.
A vernier control (0.1 to 1.0 microvolt) and a multiplier (Xl, X10, and X100) provide calibrated RF output levelS from 0.1 to 100 microvolts, available at the SIGNAL GEN. OUT connector. The output level is calibrated when using the fixed 20-db pad at the end of the RF cable supplied with the CE-3.

This connector allows use of the Cushman Model 309 Remote Meters with the CE-3. The slide switch associated with the rear-panel connector must be in the EXT. position for use of the Remote Meters, and in the INT. position for use of the CE -3 front-panel meters.
NOTE
If the CE-3 panel meters do not indicate under normal measuring conditions, the INT .-EXT. meter switch should be checked to make sure it is in the INT. position.
Model 109 Remote Meters supplied with the Model CE-2B can also be used by changing one connector on the interconnecting cable. The external deviation meter in both the Model 309 and Model 109 will function only when the Model 302 FM Deviation Meter Plug-in is being used with the CE-3.
Provides operating voltages and signals for the Cushman Model 107 FM Deviation Calibrator or Model 108 Decade Frequency Divider. These were standard accessories with the earlier Cushman FM Communication Monitors designated Model CE-2 and CE-2B; they will also operate with the Model CE-3.
3.4 Frequency and Deviation Measurement
This procedure will assume that the CE-3 is equipped with a Model 303 Broadband Mixer and either the
Model 301 Oscilloscope or the Model 302 Deviation Meter. Measurement of frequency and deviation using one
of the RF Preselectors will be the same except that the frequency dial on the appropriate Preselector must be
set to indicate approximately the dialed-in frequency.
a. Connect an external antenna or the telescoping antenna supplied with the instrument to the ANT. panel
connector. If the telescoping antenna is used, extend it to its full length for low band measurements, approximately
18 inches for high band measurements and minimum length for UHF measurements.
b. Turn the function switch to CAL.
c. Adjust the inner red knob (part of the function switch) for a zero (mid-scale) reading on the FREQUEN
CY meter.
d. If the Model 301 Oscilloscope is being used, set the toggle switches for horizontal and vertical inputs to
the INT. position and adjust the VERT. POS. control so that the trace is on the zero reference line while the
deviation rang'e switch is in the ± 1.5 position. Adjust the scope INTENSITY, FOCUS, and ASTIGMATISM
controls for a sharp trace on the CRT.
e. Change the function switch to the FREQ.-DEV. MEASURE position.
f. Dial in the transmitter's assigned frequency with the six frequency selector switches.
3-5
g. Key the transmitter being monitored. The SIGNAL LEVEL light should come on. If it does not, move
the CE-3 and the transmitter closer together until the received signal is strong enough to turn on the light.
Normally, measurements can be made easily when the CE-3 is within 25 to 50 feet of the radiating antenna.*
h. Read the transmitter frequency error directly on the FREQUENCY meter. Select one of the three meter
ranges with the lever switch just below the meter.
i. Modulate the transmitter and read the FM deviation on the FM DEVIATION meter or the Oscilloscope.
Select the desired meter or scope range with the range switch on the plug-in being used. On the oscilloscope,
positive peaks appear near the top of the display, and negative peaks near the bottom. On the Deviation Meter,
the meter will indicate either positive or negative peaks, depending on the setting of the FM DEV. PEAKS switch.
If the DEVIATION PEAKS light on the Deviation Meter plug-in has been calibrated (see Section 3.8), any instan
taneous modulation peaks which exceed the preset level can be detected. The accuracy of the FM DEVIATION
meter or Oscilloscope readings can be verified by means of the Cushman Model 107 FM Deviation Calibrator.
3.5 Using the CE-3 on "Out-of-Band" Frequencies
The CE-3 can be used to make frequency and deviation measurements as well as generate signals utilizing
second harmonics of the 450-512 MHz band. In this way measurements can be made at transmitter frequencies
between 910 and 1010 MHz. The procedure for determining the correct dialed-in frequency is as follows.
a. SUbtract 10 MHz from the required 910-1010 MHz frequency.
b. Divide the remainder by 2.
c. Dial-in the resulting quotient plus 10 MHz.
For example, assume we wish to measure a 960-MHz transmitter with the CE-3. The first step would be to sub
tract 10 MHz from the desired chalmel, which would give us 950 MHz. This difference would then be divided by
2 and the resulting quotient would be 475 MHz. Then, adding 10 MHz, we dial-in 485 MHz on the CE-3 frequency
selector. With 485 MHz dialed in, the CE-3 will respond to a signal from a 960-MHz transmitter and the fre
quency error and deviation indicated by the CE-3 will be the actual error and FM deviation of the transmitter
signal. Also, a 960-MHz sig'nal will be present at the SIGNAL GEN. OUT connector. Since the CE-3 is being
operated on a second harmonic, the calibration of the output signal in microvolts will not be as indicated on the
SIGNAL GEN. ATTEN. controls. The same procedure can be used utiliZing the second harmonics of the 10 and
hig'h bands of the CE-3 to make measurements between 80-120 MHz or 270-320 MHz,
3.6 CW Signal Generation
a. Set the six frequency selector switches to the desired channel frequency.
b. Place the function switch in the CW position.
c. A coaxial cable and 20-db pad are stored inside the hinged instrument front cover; connect the cable to
the panel connector marked SIGNAL GEN. OUT.
d. The desired channel frequency is now being generated. The output level can be adjusted by means of the
attenuator multiplier and vernier controls.
..
Whenever a direct coaxial connection is made between the CE-3 and a transceiver, extreme care must be taken to a void keying the transmitter.
* When a plug-in Preselector is being used, measurements can be made at distances up to 50 miles from the transmitter assuming the use of a proper external antenna.
3-6
3.7 FM Signal Generation
a. Set the six frequency selector switches to the desired channel frequency.
b. Place the function switch in the FM position.
c. Set the FM MOD. switch to INT. or EXT. as desired. In the INT. position the modulating frequency will
be 1 kHz; this same I-kHz signal is available at the I-kHz OUT connector for use in modulating a transmitter or
repeater. External modulation frequencies can be applied through the BNC panel connector when the switch is in
the EXT. position.
NOTE
The FREQUENCY meter will now monitor the modulator center frequency, and the FM DEVIATION meter or Oscilloscope will now indicate the amount of generated deviation.
d. Use the DEV. ADJ. and FM CAL. concentric controls to set the amount of deviation desired and to cali
brate or zero the center frequency of the modulator, as indicated on the FREQUENCY meter.
NOTE
The FM CAL. control varies the center frequency of the FM signal and allows testing of receivers for absolute "on-channel" alignment and maximum sensitivity. The deviation range of the plug-in Deviation Meter or Oscilloscope can be selected by means of a switch on the front panel of each plug-in; but the FREQUENCY meter is automatically on the ± 5-kHz range when the function switch is in the FM position, and it cannot be changed by the meter range switch.
e. Steps c and d of Section 3.6 and the caution note in that section also apply to FM signal generation.
3.8 DEVIATION PEAKS Light Calibration Adjustment
The DEVIATION PEAKS light on the Deviation Meter plug-in can be made to flash when the absolute peak
deviation exceeds a preset limit. To establish this limit and adjust the SET control, tile internal FM signal
generator is used.
a. Follow the procedure outlined in Steps a through e of Section 3.7, and adjust the DEV. ADJ. control for
the desired FM deviation trigger limit. The FM MOD. switch must be in the INT. position.
b. Turn the SET control to its maximum counterclockwise position. The DEVIATION PEAKS light should
turn on.
c. Slowly rotate the SET control clockwise until the light just goes out. The trigger level for the light is
now set at the deviation level being internally generated by the CE-3.
d. Rotate the function switch to the FREQ.-DEV. MEASURE position, and use the CE-3 in the normal way
for measuring frequency and deviation. The calibration of the DEVIATION PEAKS light is not affected by chang
ing the frequency selector to a different channel. The + or - peaks being monitored are indicated by the position
of the FM DEV. PEAKS switch.
3-7
3.9 Audio/LF. Signal Generation
a. Rotate the left frequency selector control knob to the extreme clockwise position so that LF. is indicated
in the display window. If the frequency display window light flashes on and off, this indicates a dialed-in frequen
cy out of the normal LF. ranges.
b. Set the LF. FREQUENCIES range switch to either 0-4 or 4-40 MHz, as desired.
c. Dial-in the desired LF. or audio frequency. (Audio frequencies below 1 kHz can be generated; however,
the indicated output frequency will have a slight amount of residual FM.)
d. The generated signal is available at the front-panel LF. FREQUENCIES OUTPUT connector. Its level
can be varied with the LF. LEVEL control.
e. The basic output frequency range is always 0-4 MHz, variable in 100-Hz steps. When the switch is
placed in the 4-40 MHz position, harmonics of the basic frequency are available at the LF. FREQUENCIES OUT
PUT connector. However, the predominant signal frequency will be one-tenth the indicated frequency.
3.10 Generation of Frequencies Below 100 Hz
Frequencies below 100 Hz for reed-relay selectors and other uses can be generated by using a Cushman
Model 308 Decade Frequency Divider in conjunction with the CE-3, as described in Section 1.4.

SECTION 4
CIRCUIT DESCRIPTION
4.1 General (Refer to Figure 4-1)
The Model CE-3 Communications Monitor is essentially a highly specialized VHF/UHF superheterodyne
receiver. The RF signal whose frequency is to be measured is applied through the front-panel ANT ./RF IN
connector to the broadband mixer or one of the three preselectors whichever is plugged into the CE-3, and is
then mixed with a local-oscillator signal from the frequency synthesizer. The LO frequency is selected by the
six frequency selector knobs on the front panel, and is automatically displaced exactly 10 MHz from the frequency
indicated by the illuminated numbers associated with the knobs. Thus, if the frequency of the monitored signal is
exactly equal to the frequency indicated on the frequency selector knobs, the output of the mixer will be exactly
10 MHz.
After amplification, the la-MHz signal is heterodyned in a second mixer with a fixed-frequency 9.9-MHz
signal derived from the Synthesizer to produce a lOa-kHz signal, which is amplified and applied to a disc.rimi
nator (frequency-error detector) circuit. The squelch detector in the Broadband Mixer or Preselector rectifies
the I.F. signal, and feeds the resulting dc voltage to the signal level detector on the 2nd I.F. and Discriminator
board. When the I.F. signal exceeds a preset level, the signal level detector lights the front-panel SIGNAL
LEVE L lamp and turns on the frequency-error detector. The frequency-error detector is adjusted to give a
zero indication on the FREQUENCY meter when the input to the detector is exactly 100 kHz. If the frequency of
the monitored signal is above or below the frequency set on the frequency selector knobs, the input to the
frequency-error detector will be above or below 100 kHz; and the detector output will cause the FREQUENCY
meter to deflect toward the + or - side, indicating the direction and amount of frequency error.
If the monitored signal is frequency modulated, the modulation will be present in the output of the frequency
error detector. This modulation is amplified and fed to either the Model 302 Deviation Meter circuit or to the
Model 301 Oscilloscope eircuit, whichever is plugged in. If the Model 302 is plugged in, its FM DEVIATION
meter will indicate the peak deviation of the FM signal. The output of the deviation meter circuit is also fed to
a front-panel SCOPE connector; an oscilloscope connected to this output enables the operator to observe the
modulation on the monitored signal. In addition, a built-in speaker fed from the discriminator permits aural
monitoring of the signal.
If the Model 301 Oscilloscope, rather than the Model 302 Deviation Meter, is plugged in, the amount of peak
to-peak frequency deviation can be read directly on the oscilloscope.
The Model CE-3 Monitor can also be used to generate a CWOI' FM signal. The frequency of the generated
signal is setup by means of the frequency selector knobs, and is indicated by the illuminated readout immediately
above the knobs. For CW signal generation, a la-MHz signal from the frequency synthesizer is heterodyned in
the signal generator mixer with a frequency offset 10 MHz from that selected by the frequency selector knobs to
produce an output signal whose frequency is that indicated by the illuminated readout. For FM signal generation,
a la-MHz FM signal is generated internally and applied to the signal generator mixer to produce an FM output
signal whose frequency is that indicated by the readouts; this signal can be modulated by a I-kHz signal from the
frequency synthesizer, or by an external audio signal fed in through the front-panel EXT MOD IN/I KHZ OUT
connector. In either case, the amount of FM deviation is adjustable by the front-panel DEV. ADJ. control, and
is read on the FM DEVIATION meter or Model 301 oscilloscope in the same way as when monitorong an incoming
RF signal. When the front-panel FM MOD. switch is in the !NT position, the I-kHz signal from the Synthesizer
is delivered to the EXT MOD IN/I KHZ OUT connector for external use and the DEV. ADJ. control will vary the
output level.

The 10-MHz signal, regardless of whether it is CW or FM, is fed to the Signal Generator Mixer through a
precision attenuator, which is calibrated so that the output level can be read directly from the front-panel
SIGNAL GEN. ATTEN. controls when the 20-db pad supplied with the CE-3 is used at the SIGNAL GEN. OUT
connector.
In addition to its RF outputs, the Synthesizer generates audio and LF. outputs which are available at the
front-panel LF. FREQUENCIES OUTPUT connector. The amplitude of this output signal is adjustable by the
front-panel LF. LEVEL control. The output frequency is adjustable by means of the frequency selector knobs,
and a selector switch permits a choice between a fundamental frequency range of 1 kHz to 4 MHz or a harmonic
range of 4 to 40 MHz.
All Synthesizer frequencies are derived from a precision 3-MHz crystal maintained at a constant tempera
ture. The process by which the Synthesizer output frequencies are produced is described in Section 4.2.
4.2 Frequency Synthesizer
The principal functions of the Frequency Synthesizer are to produce a variable La signal for the receiver's
1st mixer and the Signal Generator Mixer, and a fixed 9.9-MHz La signal for the receiver's 2nd mixer (see
Figure 4-1). These La frequencies are very precisely generated in order to achieve the Monitor's rated accu
racy. The variable La frequencies are chosen by the front-panel frequency selector knobs, as described in
Section 4.1.
The Frequency Synthesizer also supplies a 10-MHz input to the Signal Generator Mixer, a I-kHz input to the
Modulator, and a variable frequency in the range of 0 to 4 MHz to the front-panel LF. FREQUENCIES OUTPUT
connector.
All of the Synthesizer frequencies are derived from a 3-MHz Master Oscillator whose frequency is deter
mined by a precision crystal maintained at a constant temperature in a thermostatically controlled oven. As
shown in the Synthesizer block diagram, Figure 4-2, the master-oscillator frequency is divided by 3 to obtain a
basic I-MHz frequency.
Although the Master Oscillator is the circuit which establishes the frequency accuracy of the Synthesizer,
the variable-frequency output signals are actually generated by a Voltage-Controlled Oscillator (VCO), which is
phase-locked with the Master Oscillator. The required VCO frequenCies corresponding to the frequency selector
knob settings are given in Table 4-1. For example, if the dialed-in frequency were 123.456 MHz, the required
VCO frequency would be 6.3456 MHz. The VCO is set up to within 100 kHz of its required frequency by the first
three frequency selector switches; in the example above, the first three frequency selector switches would adjust
the VCO to a frequency within the range of 6.3000 to 6.4000 MHz. The VCO is set exactly on the required fre
quency by sampling the VCO output 100 Hz and comparing its frequency with a 100 Hz signal derived from the
precision Master Oscillator; any difference in these frequencies produces a correction voltage which is applied
to the Varicap in the VCO, causing the Varicap to tune the VCO over a 100-kHz range until the frequency differ
ence is zero. The way in which this is done is described in the following paragraphs, and in more detail in the
sections dealing with the VCO (Section 4.2.3), the ~ N Counter (Section 4.2.4), the Sample and Hold Circuits
(Section 4.2.5), and the Phase Detector (Section 4.2.2).
The VCO output is fed into a ~ N Counter, which is programed by the frequency selector knobs (2nd digit
through the 6th digit) to produce a reset pulse every time the Counter reaches the total count represented by the
digits of the required VCO frequency. For example, using the frequencies of the preceding paragraph, the -;- N
Counter would produce a reset pulse every time it counted 63,456 input pulses. Since the input to the Counter
in this example is 6.3456 MHz (assuming the VCO is exactly on frequency), there would be 6,345,600 pulses per

second applied to the Counter, causing it to reset after 63,456 input pulses are counted for a 100 Hz output. The
relationship between VCO frequency and knob settings of the -:- N Counter is as following:
Actual VCO Frequency (in Hz) = Counter Setting x 100
The Counter reset pulses are applied through a delay network to one input of a Phase Detector; the other
input is a precise 100-Hz signal produced from the basic I-MHz signal by the Reference Divider. The Phase
Detector consists of a R. S. Flip-Flop which is switched high by a pulse from the Reference Divider and switched
low again by the next pulse from the -:- N Counter. Thus, the width of the waveform out of the Phase Detector is
determined by the phase differential between the two input pulses. The Phase Detector drives a ramp generator
which produces an output whose amplitude is proportional to the width of the Phase Detector output waveform.
This amplitude is sampled once every 10 m sec. If the VCO frequency is exactly in phase with the reference
frequency, the sampled voltage will be constant and of the correct value to hold the VCO on frequency; if the
VCO is out of phase with the reference frequency, the sampled voltage will cause a correction voltage to be
applied to the VCO to bring it back into phase lock.
The VCO output is fed to the Balanced Mixer, where it is added to either 40 MHz or 42 MHz, depending on
the setting of the 1st-digit frequency selector knob (see Table 4-1). The resulting signal, in the range of 46.0 to
50.2 MHz, is multiplied by 10, filtered, and applied to the UHF Matrix. A 330-MHz signal and a 430-MHz signal
are also applied to the Matrix in certain positions of the 1st-digit switch (see Figure 4-2 and Table 4-1). The
UHF Matrix is simply a diode switching network; the 460-502 MHz signal is always fed through it, but the 330
MHz and 430-MHz signals are fed through only when the 1st-digit switch applies a forward bias to the appropriate
diode. (For simplicity, Figure 4-2 shows the 1st-digit switch in the RF signal line.) The output of the Frequency
4-5
Synthesizer, then, is a signal in the range of 460-502 MHz in all positions of the 1st-digit switch, plus a 430
MHz signal when the 1st-digit switch is in position 0 or a 330-MHz signal when the 1st-digit switch is in position
1. In the Broadband Mixer or Preselector, these frequencies are combined with the received signal to produce
a 10-MHz LF., as described in the Model 303, 304, 305, and 306 manuals. In the CAL., CW, and FM modes of
operation, the Frequency Synthesizer outputs are combined with a fixed 10-MHz signal in the Signal Generator
Mixer to generate the dialed-in frequency.
When the 1st-digit frequency selector switch is in the LF. position, the 46-50 MHz output of the Balanced
Mixer is combined in a difference mixer with a fixed 46-MHz signal to produce the 0-4 MHz I.F. output. Table
4-2 gives the frequency relationships involved.

Notes: 1. 1st-digit frequency selector knob is on "I.F."
2. Fixed-frequency input to Balanced Mixer is always 40 MHz for I.F. signal generation.
Most of the mixing frequencies used in the Synthesizer are produced by applying either the 3-MHz output of
the Master Oscillator or the I-MHz basic frequency to harmonic generators, and filtering the output of these
generators to obtain the desired frequency. The 10-MHz output for the CW and CAL. functions and the 9.9-MHz
output for the receiver's 2nd mixer are obtained in the same way. To derive the 43-MHz and 46-MHz mixing
signals, the 3-MHz output of the Master Oscillator is applied to a mixer, the other input of which is 40 MHz.
The fundamental of the 3-MHz input adds to the 40-MHz signal to produce the 43-MHz output, and the second
harmonic of the 3-MHz input adds to the 40-MHz signal to produce the 46-MHz output.
4.2.1 Master Oscillator, Divider, and Filters (CH-A17). The master oscillator generates the signal from which
all the Synthesizer frequencies are derived. This board, CH-A17, provides the following outputs:
a. A I-MHz signal for the Reference Divider.
b. A 3-MHz sine-wave signal for the 43-MHz/46-MHz mixer.
c. A 3-MHz pulse signal for the 33-MHz and 42-MHz Harmonic Generators.
d. A 10-MHz signal for calibrating the discriminator and CW signal generation.
e. A 20-MHz signal for the 40-MHz doubler.
As shown in the schematic diagram, Figure 6-1, Ql is the crystal oscillator. The 3-MHz crystal, which is
mounted in an oven separate from Board CH-A17, is in the base circuit of Ql, which is a modified Pierce oscil
lator. The output is fed through untuned isolation amplifier Q2 to IC2, and also to pin 4 of the board connector
as the 3-MHz sine-wave output of the board. IC2 is a pulse-shaping circuit, which changes the 3-MHz sine wave
to a square wave.
The 3-MHz pulse output of IC2 is fed to pin 7 of the board connector as the 3-MHz pulse output of the board;
it is also applied to the input of IC 1, which is a pair of JK flip-flops connected as a counter. The interconnections
are such that the second flip-Hop produces one output pulse for every three input pulses to the first flip-flop, thus
dividing the 3-MHz input to 1 MHz. The I-MHz signal is fed through wave-shaping circuit IC3 to the 10-MHz and
4-6
20-MHz filters; the l-MHz signal is also fed through pin 13 of the board connector to the Reference Divider on
Board CH-A9.
Transistor stages Q3, Q5, Q7, Q8 and Q9 constitute an active filter tuned to 20 MHz. Stages Q8 and Q9 make
up a similar filter tuned to 10 MHz.
4.2.2 Reference Divider and Phase Detector (CH-A9). This board contains a Reference Divider to divide the
I-MHz basic frequency down to 100 kHz, 1 kHz, and 100 HZ; and a Phase Detector to compare the IOO-Hz signal
from the -:- N Counter with the precise 100-Hz signal. from the Reference Divider, and to produce an output pulse
whose width depends on the phase difference between the two input signals.
The Reference Divider circuit is shown at the top of the board schematic diagram, Figure 6-2. The I-MHz
signal from the -:- 3 circuit on the Master Oscillator board is applied to an integrated-circuit decade counter,
ICI. The 100-kHz output of ICI is fed through buffer IC9 to pin 4 of the output connector; this signal is also
applied through buffer amplifier IC3 to the second decade counter, IC5. The resulting IO-kHz output of IC5 is
applied to decade counter IC7 to produce a I-kHz signal. This I-kHz signal is fed through one NAND gate of
IC 10, which acts as a buffer amplifier, to pin 9 of the output connector; it also drives the fourth decade counter,
IC8. The IOO-Hz output of IC8, after being shaped in ICIO, appears as the "set" input to the Phase Detector flip
flop, IC2.
The Phase Detector circuit is shown on the bottom half of Figure 6-2. Pulses with a PRF of 100 Hz from
the Reference Divider are applied to "set" terminal 6 of flip-flop IC2; pulses with a PRF of 100 Hz from the
-:- N Counter are applied to "reset" terminal 5 of the flip-flop. A Reference Divider pulse turns the flip-flop on,
and the next -:- N Counter pulse turns it off. The width of the flip-flop output waveform at terminal 11 is con
stant and of the right magnitude to hold the VCO on frequency only when the two input pulses are in phase. This
output of the flip-flop (the Q output) is fed through one of the NAND gates of IC4, acting as a buffer stage, to the
Sample and Hold circuit through pin 11 of the output connector.
4.2.3 Voltage-Controlled Oscillator (CH-A2I). The VCO produces a signal in the range of 6 to 10 MHz; its exact
frequency is related to the settings of the frequency selector switches in accordance with Table 4-1. The VCO
is phase-locked with the Master Oscillator so that its output frequency is as accurate as that of the Master
Oscillator.
As shown in the block diagram, Figure 4-3, four separate tank circuits are used with oscillator Q, which is
tuned by Varicap CR2 in parallel with a capacitance selected by the 3rd-digit frequency selector switch. The tank
circuit to be used is turned on by the 1st-digit and 2nd-digit frequency selector switches in combination, as
shown by the table of Figure 4-3. The 3rd-digit switch selects a capacitance to tune the oscillator to within 100
kHz of the required frequency; thus, if the required VCO frequency is 6.3456 MHz (6345.6 kHZ), the capacitance
selected by the 3rd-digit switch would tune tank circuit 6-7 MHz to a frequency between 6300 and 6400 kHz. Fur
ther tuning within this IOO-kHz range is done by a dc error signal applied to the Varicap from the Sample and
Hold circuit.
The oscillator output is fed through emitter follower Q3 to the Balanced Mixer. The phase-inverted signal
at the collector of Q3 is fed through emitter follower Q2 to the 7- N Counter.
Figure 6-3 is the schematic diagram of the VCO. The oscillator, QI is a Colpitts-type. The tuned circuits
consist of a variable inductor in parallel with fixed capacitors. In addition, the operating oscillator has a pair of
capacitors (one fixed and one trimmer) selected by the 3rd-digit switch plus the Varicap with its trimmer added
in parallel with the tank circuit. A tuned circuit is turned on by a ground from the combined 1st-digit and 2nd
digit switches; the ground closes the diode switches in the tank circuits.

4.2.4 -:- N Counter (CH-A12, CH-A13, and CH-All)
4.2.4.1 Overall Operation. The -:- N Counter must produce an output pulse every time it reaches the total count
preset by the digits of the required VCO frequency. Figures 6-4, 6-5, and 6-6 are the schematic diagrams
and Figure 4-4 is the block diagram of the -:- N Counter. Each decade counter is originally set by the frequency
selector switches to a count equal to 9 minus the corresponding number for that decade in the required VCO
frequency.* Thus, for a required VCO frequency of 6.8765 MHz, the decades would be originally set as follows:
Decade 1 9 5 4
Decade 2 9 - 6 - 3
Decade 3 9 - 7 2
Decade 4 9 - 8
Decade 5 9 6 3
The way in which this is done is explained in Section 4.2.4.4.
The sine-wave output of the VCO is applied to the clock pulse-forming circuit, which produces a square wave
synchronized with the VCO frequency. This square wave is applied to the 1st decade; since this decade (in our
example) has been set to an initial count of 4, the first clock pulse would advance it to a count of 5. After the
5th input pulse, the first decade would be in binary state 9 (see Table 4-3). The next clock pulse, the 6th from
the start, would cause Decade 1 to reset to 0 and at the same time would trigger Decade 2. Decade 2 had pre
viously been reset to binary state 3; when the first trigger arrives, Decade 2 advances to binary state 4. This
procedure is repeated until all decades except Decade 1 reach binary state 9, and until Decade 1 reaches binary
state 8. At this point, a total of N-1 clock pulses have been counted (where N is the number of counts for which
the -:- N Counter has been set).
In binary state 9, a decade's A and D outputs are high; and this is the only binary state in which these two
are high. Also, just before reaching binary state 8, AI' B1' and C1 of Decade 1 are high. Thus, at this instant,
all inputs to the multi-AND gate are high. This sets up a flip-flop in the reset pulse-forming circuit. When the
8th clock pulse falls, the reset flip-flop is triggered and produces a reset pulse, resetting all decades to their
original condition. When the next clock pulse arrives (total count =N), all decades are being reset; so no count
occurs. On the following clock pulse, the first count of the new counting cycle starts.
The reset pulse has two functions: to reset all decades to their original conditions, and to appear as the
output of the -:- N Counter. Table 4-3 shows the binary state resulting from each clock pulse for an example in
which the required VCO frequency is 6.8765 MHz.
4.2.4.2 Decade Operation. As shown in Figure 4-4, the -:- N Counter comprises five decade counters. Each
decade counts up to binary state 9, then is reset to binary state 0 and triggers the next decade, then starts
counting again at binary state 1. Each decade is preset to a particular binary state, as mentioned in Section
4.2.4.1; the process by which they are preset is described in Section 4.2.4.4. Since the operation of the first
four decades is essentially the same, only one will be discussed here.
* The decades are actually preset by the first reset pulse produced by the -:- N Counter, and are reset to the preset number by each succeeding reset pulse.

Figure 4-5 is a block diagram and timing diagram of a typical decade. The decade consists of four J-K
flip-flops and a pair of NAND gates, as shown. The J -K flip-flops operate as follows:
a. Q is one of two outputs.
b. Q is the other output; it is 1 when Q is 0, and is 0 when Q is 1.
c. T is the toggle input; the falling edge of the input pulse at T, under control of J and K, causes the flip-flop to change states.
d. J is the control input for Q; when J is 1 or floating, Q can switch to 1.
e. K is the control input for Q; when K is 1 or floating, Q can switch to 1.
f. S (set) is a direct input, independent of the toggle; when low, it sets Q to 1.
g. R (reset) is a direct input, independent of the toggle; when low, it sets Q to 1 directly and resets Q to O.
The NAND gates operate as follows:
a. When both inputs are 1, output is O.
b. When either or both inputs are 0, output is 1.
For this discussion of decade operation, assume that the decade has been reset to binary state 0, so that
all flip-flops are at binary low (0). J of A will be 1; so when the input to T of flip-flop A falls, Q of A switches-to 1. K of A is also 1; so when the second pulse at T of A falls, Q of A rises to 1, forcing Q of A to O. When
Q of A drops to 0, it provides a toggle to flip-flop B. J of B is 1 because flip-flop D was reset to 0 as an initial
condition, making Q of D (and hence J of B) 1; therefore Q of B will change state to 1 when B is toggled.
On the third input, flip-flop A is again toggled high. On the fourth input, Q of A drops, causing flip-flop B to
change states. The falling pulse from Q of B causes Q of C to become 1. The flip-flops operate as shown in the
timing diagram through the 6th input.
Before the 6th input, Q of Band Q of C have not been high at the same time. Thus, the output of the first
NAND gate has been 1, and the output of the 2nd NAND gate (a simple inverter) has been O. Therefore, J of D
has been 0, and flip-flop D has not been able to switch states. After the 6th input, however, Q of Band Q of C
are both 1, making J of D high; so the next time Q of A falls, which is after the 8th input, Q of D goes to 1. Then,
on the 10th input, when Q of A falls, D is toggled back to O. Flip-flop B would normally be toggled by flip-flop A
to 1 on the 10th input; however, when flip-flop D goes to 1 on the 8th input, Q of D goes to 0, and this places a 0
on J of B, preventing B from toggling.
All flip-flops are now reset to 0 and ready to begin a new count to 10. Note that the reset within the decade
itself always resets the decade to binary state O. The reset pulse from the output of the 7 N Counter resets
each decade to a preset count, as explained in Section 4.2.4.1.
When flip-flop D goes to 1 in binary state 8, it drives J and K of the first flip-flop in the next decade to 1.
Then, when Q of A falls to 0, it triggers the first flip-flop in the next decade. Thus, when a decade goes from
binary state 9 to binary state 0, it triggers the next decade.
4.2.4.3 Reset Pulse-Forming Operation. The reset pulse-forming circuit must generate a pulse when Decades
2 through 5 are in binary state 9 and Decade 1 reaches binary state 8. In Figure 4-5 it is seen that the A and D
outputs of Decades 2 through 5 are 1 in binary state 9; these outputs are fed to a multi-AND circuit. As seen in
Figure 4-6, this multi-AND consists of four NAND gates plus the AND gate at the J input of the reset flip-flop.
Outputs A, B, and C of Decade 1 are high in binary state 7; so when Decades 2 through 5 are in binary state 9
and Decade 1 is in binary state 7, all inputs to J of the reset flip-flop are high. K of the reset flip-flop is held

high by the applied positive voltage. Q of the reset flip-flop is high, having been set to that level by the preced
ing reset operation; therefore, Q is low. Under these conditions, the next (8th) clock pulse toggles Q to 1, forcing
Q to O.
As shown in Figure 4-6, Q of the reset flip-,flop feeds a pair of power gates; when Q goes to 0, the power
gate outputs go to 1. This is the reset pulse.
4.2.4.4 Decade Preset Operation. As stated in Section 4.2.4.1, each decade must be reset by the -:- N Counter
reset pulse to a binary state which is 9 minus the corresponding number for that decade in the required VCO
frequency.
Figure 4-7 illustrates the resetting operation for Decades 1 through 4. Consider the operation of flip-flop
A in Decade 1. The Sand R inputs to the flip-flop come from a pair of NAND gates. One input of each NAND
gate is driven by the reset circuit; these two inputs will be 1 during the reset pulse. The other input to the
NAND gates comes from one deck of the 6th-digit switch; this input will be either 0 (ground) or 1, depending on
the switch position. The pair of NAND gates are interconnected so that when the switch input is 0, the S input of
the flip-flop will be 0 and the R input will be 1; and also when the switch input is 1, S will be 1 and R will be O.
Thus the output (terminal Q) of the flip-flop is positively determined during reset by the switch position. The
table in Figure 4-7 gives the Q output of flip-flop A for each position of the 6th-digit switch.
The other three flip-flops of Decade 1 are reset in a similar way, the only difference being in the switch
inputs. The table of Figure 4-7 shows the output of each flip-flop in Decade 1 for each position of the 6th-digit
switch, and the resulting binary state of the decade. For the example of Table 4-3, in which the 6th-digit switch
is set on 5 and a preset binary state of 4 is required, it can be seen from the table of Figure 4-7 that flip-flops
A through D will have outputs of 0, 0, 1, and 0, respectively, corresponding to a binary state of 4.
The discussion so far has been on Decade 1, but Decades 2, 3, and 4 are reset in the same way according to
the positions of the 5th-digit, 4th-digit, and 3rd-digit switches, respectively. The tabulation of Figure 4-7 is
valid {or all of these decades.
Decade 5 requires a slightly different reset circuit because the first number in the VCO frequency is not
determined by a single frequency selector switch; rather, it depends on the setting of both the 1st-digit and
2nd-digit frequency selector switches.
As shown by Table 4-1, the first number of the VCO frequency must be 6, 7, 8, or 9. Thus, the 5th decade
must be preset to binary state 3, 2, 1, or O. The binary representations of these preset states are 0011, 0010,
0001,0000, respectively. From this, it can be seen that flip-flops D and C will always be preset to 0, and that
flip-flops A and B must be preset as follows:
First Number Required 5th Decade of VCO Freq. Preset State Flip-Flop A Flip-Flop B
6 3 1 1 7 2 0 1 8 1 1 0 9 0 0 0
Figure 4-8 is a block diagram of the Decade 5 reset circuit. The switching voltages coming in through
terminals U, V, and Ware 0 (ground) when the first number of the VCO frequency is 6, 7, and 8, respectively;
the table in Figure 4-8 shows the combination of 1st-digit and 2nd-digit switch positions that produce these
grounds.

The reset pulse is brought in through terminal X, SO that one input of NAND gates NG1 through NG4 is 1
during reset. If a ground is present on the "6" or "8" switch lines, the output of OR gate OG1'" will be 1, pro
ducing a 0 output from NG2 and therefore a 1 output from A5,*'" as required. Similarly, a ground on lines "6"
or "7" produces a 1 from B5, as is also required. All other switch settings result in outputs of 0 from A5 and
B5' Flip-flops C5 and D5 are held to a 0 output during reset by a fixed voltage at their S terminals and a 0
input to their R terminals from NAND gates NG5 and NG6.
4.2.5 Sample and Hold Circuits (CH - A 10). The Sample and Hold Circuits develop a dc error voltage for the
VCO which is proportional to the phase difference between the output of the -:- N Counter and a precise 100-Hz
signal from the Reference Divider.
*The output of an OR gate is 1 if either of its inputs is 0; the output is 0 if both of its inputs are 1.
** The notation "A 5" means flip-flop A in Decade 5.
4-17
Figure 4-9 is a simplified block diagram of the Sample and Hold Circuits. As described in Section 4.2.4,
a pulse from the Reference Divider turns on the Phase Detector flip-flop; this is shown on lines 1 and 2 of the
timing diagram at the bottom of Figure 4-9. The output of the Phase Detector is applied to a ramp generator on
the Sample and Hold board. The output of the ramp generator is a waveform with a constant slope (line 3 of the
timing diagram). When a pulse is received from the '-:- N Counter (line 4) it switches on the first Sample and
Hold Circuit for the duration of the -:- N Counter pulse. Capacitor C12 charges to the ramp voltage, which is
continuing to decrease; so the voltage on C12 has the shape shown on line 5 of the timing diagram. Although the
voltage on C12 varies as shown, between sampling periods the capacitor stays charged to the voltage present at
the end of the preceding sampling period. Thus, the dc level on C12 depends on the phase difference between the
Reference Divider pulses and the -:- N Counter pulses.
The pulse from the -:- N Counter is delayed 500 microseconds by a circuit on the Sample and Hold board,
and is then fed to the Phase Detector flip-flop to turn it off.
The voltage on C 12 is not suitable for controlling the VCO because of the ripple produced on it during' the
sampling process. Therefore, a second Sample and Hold Circuit, turned on by the delayed -:- N Counter pulse,
samples the voltage on C12 immediately after the first sampling period, and places this voltage on capacitor C13.
Since the voltage sampled is constant (in case there is no phase error) or slowly changing (in case of a phase
error), the voltage on C13 will not contain a ripple. This voltage is applied to a high-impedance level detector,
Q9, which feeds an input to dc amplifier IC4 that is proportional to the voltage on C13. IC4 is an operational
amplifier whose output is directly proportional to its input. The output of IC4 is the dc error voltage for the
VCO.
The ramp generator consists of stages Ql through Q4 (see the schematic diagram, Figure 6-7). The rec
tangular waveform from the Phase Detector flip-flop is inverted and amplified by Ql and applied to the bootstrap
timing' circuit consisting of Q2, Q3, and Q4. The resulting linear sawtooth at the emitter of Q4 is fed to the drain
of field-effect transistor Q5. When the positive pulse from the -:-N Counter is applied through amplifiers Q7 and
Q6 to the gate of Q5, Q5 is turned on and feeds the sawtooth to capacitor C12. A similar circuit, consisting of
Q8, QI0, and Qll, performs the second sampling operation. Q9 is a metal-oxide-semiconductor (MOS) field
effect transistor, which presents a very high shunt resistance across capacitor C13 so that the charge on C13
will not leak off appreciably between sampling periods. The output of Q9 is fed through integrated-circuit
operational amplifier IC4, which has a fixed gain of 2.1, to pin Y of the output connector.
The lower half of Figure 6-7 is the 500-microsecond delay circuit. ICI is a one-shot multivibrator. When
it is triggered J;ly the leading edge of the -:- N Counter pulse, it produces an output voltage at terminal 6 for a
period of 500 microseconds. This rectangular waveform is inverted by Q8, and the trailing' edge used to trigger -a second one-shot multivibrator, IC2. The output of IC2, a pulse approximately 350 microseconds wide, is fed
through buffer stage IC3 to the second Sample and Hold Circuit, and also to the Phase Detector through pin 19
of the output connector.
4.2.6 40-MHz, 43-MHz, and 46-MHz Filters (CH-AI8). As shown in the Frequency Synthesizer block diagram,
Figure 4-2, this board converts 20-MHz and 3-MHz frequencies from the Master Oscillator board into 40, 43,
and 46 MHz. The frequency of the 20-MHz signal from the Master Oscillator board is doubled to 40-MHz by Ql,
and fed through isolation amplifier Q2 to pin 15 of the output connector (see schematic diagram, Figure 6-8).
The dc power to Q2 is turned on by the Ist- digit frequency selector switch in the 0, 1, 4, and LF. positions,
since 40 MHz is required by the Balanced Mixer for those ranges.
The 40-MHz output of Q1 is also fed through amplifier Q3 to mixer CR2/CR3, where it is combined with a
3-MHz signal from the Master Oscillator. The output of the mixer contains both 43 MHz and 46 MHz. The

43-MHz signal is fed through an active filter (Q4, Q6, Q8 and Q10) to pin 22 of the output connector. Power is
applied to this filter only when the 1st-digit frequency selector switch is in position O.
The 46-MHz output of the mixer is fed through a similar active filter to pin 2 of the output connector; this
filter is turned on in the LF. position of the 1st-digit switch.
4.2.7 33-MHz and 42-MHz Filters (CH-A16). This board develops 33-MHz and 42-MHz outputs from a 3-MHz
input. As shown in the schematic diagram, Figure 6-9, the 3-MHz pulse signal from the Master Oscillator is
passed through pulse shaper IC2 to obtain narrow pulses, which are then applied to the inputs of two similar
tuned filters. The 42-MHz filter, Q1 through Q4, is turned on by the 1st - digit frequency selector switch in
position 5 only. The 33-MHz filter, Q5 through Q8, is activated in position 1 only.
4.2.8 Balanced Mixer (CH-A15). The Balanced Mixer adds either 40 or 42 MHz to the VCO frequency to produce
the required output (see Table 4-1). Both the 40-MHz and 42-MHz inputs are brought in through pin 2 of the
board connector; only one source will be activated at a time, as described in Sections 4.2.6 and 4.2.7. The 40
l\1Hz or 42-MHz signal is fed through tuned amplifier Q2 to the primary of mixer transformer T1.
The VCO signal is brought in through pin 11 of the board connector (Figure 6-10) and amplified by integrated
circuit amplifier IC 1. The gain of this amplifier is automatically controlled by a dc signal from a level detector
on the input of the 46.0-50.2 X10 Multiplier. This dc signal is amplified by integrated amplifier IC2 and applied
to pin 1 of IC 1. The output of IC 1 is fed through emitter follower Q1 and a low-pass filter to transformer T2 in
the balanced mixer. The output of the balanced mixer passes through the broadband filter, Q3 and Q4, to pin 21
of the board connector, and an attenuated output is delivered to pin 18 of the connector. The filter is tuned so
that it passes only the mixer products in the range of 46.0 to 50.2 MHz.
4.2.9 X10 Multipliers (CH-A2,CH-A3, CH-A4). Figure 6-11 is the schematic diagram of the X10 Multiplier for
the 46.0-50.2 MHz input. The signal from the Balanced Mixer is applied to the primary of transformer T1. A
pair of diodes (CR2 and CR3) connected as a full-wave rectifier in the transformer secondary circuit produce an
output with a strong second-harmonic content. After three stages of tuned amplification, the signal is applied to
snap diode CR4, a nonlinear device whose very fast turnoff characteristic makes it an efficient harmonic gener
ator. The input signal is also rectified by CR1 to produce a dc voltage proportional to the amplitude of the in
coming signal. This dc voltage is fed back to the Balanced Mixer board to control the gain of the VCO amplifier,
as described in Section 4.2.8.
The X10 Multipliers for the 330-MHz and 430-MHz signals are almost the same, the oniy difference being in
the value of a few components (see Figures 6-12 and 6-13). Both of these Multipliers are also very similar to
the 46.0-50.2 MHz X10 Multiplier, the chief differences being that the full-wave frequency-doubling circuit and
the signal level detector are not used in the 330-MHz and 430-MHz Multipliers.
4.2.10 UHF Matrix (CH-A1). As shown in the Frequency Synthesizer block diagram, Figure 4-2, and in Table
4-1, the Frequency Synthesizer is required to have the following 0utputS:
Frequency Synthesizer Output
Dialed-in Range From VCO Fixed Frequency
20 - 80 MHz 460-500 MHz 430 MHz 120 180 MHz 460-500 MHz 330 MHz 450 - 512 MHz 460-502 MHz None
The UHF Matrix provides the RF switching to accomplish this. Figure 6-14 is the schematic diagram. For the
20-80 MHz range, the 1st-digit frequency selector switch in the 0 position applies -12 volts to the cathode of CR1,
4-20
forward-biasing it and thus switching in the 430-MHz signal. Similarly, when the 1st-digit frequency selector
switch is in position 1, it forward-biases CR2, thus switching in the 330-MHz signal. Actual mixing of the signals
takes place in the Signal Generator Mixer and in the Broadband Mixer or Preselector, whichever is plugged into
the CE-3.
4.2.11 0-4 MHz Mixer and 9.9-MHz Mixer (CH-A8). The 46.0-50.2 MHz signal from the Balanced Mixer is
mixed on this board with a 46-MHz signal from the 46-MHz filter to produce a difference-frequency output in the
I.F. range. As shown at the top of the schematic diagram, Figure 6-15, the 46-MHz signal is fed through tuned
common-base amplifier Q1 and transformer T1 to mixer CR1/CR2. The variable frequency from the Balanced
Mixer is brought in to the center tap of the T 1 secondary. The resultant difference frequency, in the range of
0-4 MHz, is amplified by Q2 and Q3 and delivered through emitter follower Q4 to pin 10 of the board connector.
When the front-panel I.F. FREQUENCIES switch is turned to the 4-40 MHz position, a diode half-wave rectifier
is inserted in series with the I.F. output to provide harmonic operation.
The circuit at the bottom of Figure 6-15 is the 9.9-MHz harmonic generator and filter. The 100-kHz signal
from the Reference Divider is brought in at pin 21 of the board connector. Common-base amplifiers Q5 through
Q8 are tuned to the 33rd harmonic of the input frequency, and the 3.3-MHz output of Q8 is tripled in Q9 to give
the required 9.9-MHz output at connector pin S.
4.3 Second I.F. and Discriminator Circuits (CH-A20)
These circuits can be conveniently divided functionally as follows:
a. Second-mixer circuits, which amplify the 10-MHz I.F. signal from the Broadband Mixer or Preselector,
amplify the 9.9-MHz signal from the Synthesizer, and then mix them to produce a second I.F. which is nominally
100 kHz.
b. A discriminator or frequency-error detector, which delivers a voltage to the FREQUENCY meter when
the second I.F. is not exactly 100 kHz.
c. Audio circuits, which extract the modulation from the 100-kHz signal and deliver it to the speaker
circuits and to either the Model 302 Deviation Meter or the Model 301 Oscilloscope.
d. A signal-level detector, which disables the frequency-error detector until a sufficiently strong signal is
received by the CE-3, and then turns on both the frequency-error detector and the SIGNAL LEVEL lamp when
the signal level is high enough for satisfactory measurement.
Figure 4-10 is a block diagram of the Second I.F. and Discriminator Circuits.
4.3.1 Second Mixer. As shown in Figure 4-10 and in the schematic diagram, Figure 6-16, the 10-MHz signal
from the Broadband Mixer or Preselector is amplified by tuned integrated-circuit amplifier IC 1 and applied to
pin 1 of IC2. The 9.9-MHz LO signal from the Frequency Synthesizer is amplified by tuned common-base
amplifier Q1 and applied to pin 2 of IC2. Integrated circuit IC2 is connected as a mixer; its 100-kHz output is
fed through a low-pass filter to the base of Q2 in the frequency error detector.
4.3.2 Frequency-Error Detector. The 100-kHz signal from mixer IC2 is amplified by Q2 and applied to squaring
circuit Q3. The resulting 100-kHz square wave is differentiated by R20/C22 and the positive pulses from the
differentiating circuit are passed by CR1 to trigger the one-shot multivibrator, Q6/Q9. The one-shot will oper
ate if the received signal is strong enough for the signal-level detector to furnish an enabling ground to the
emitters ofQ6 andQ9 (see Section 4.3.4). Circuit constants of the one-shot multivibrator are such that each
trigger produces an output pulse whose width is one-half the period of a 100-kHz square wave (5 microseconds).

This pulse width remains 5 microseconds throughout a frequency error range of more than 25 kHz on either side
of 100 kHz. The outputs from the collectors of the one-shot transistors are fed to a bridge circuit.
Figure 4-11 is a simplified diagram of the bridge circuit, in which the one-shot transistors are represented
as switches. The switches are shown in the untriggered condition, with Q6 off and Q9 on. The voltage* at point
X is approximately +20 volts, and at point Y is about 6 volts.
Refer now to the waveforms at the bottom of Figure 4-11, and consider the case in which the frequency of
the signal from the second mixer (fin) is exactly 100 kHz. When the one-shot is triggered, Q6 is turned on,
causing X to drop to minimum voltage; and Q9 is turned off, causing Y to rise to maximum voltage. The one-shot
remains in this state for 5 microseconds and then returns to its quiescent state for 5 microseconds before it is
triggered again, as shown in the X and Y waveforms of Figure 4-11. The square-wave voltages at X and Yare
passed through averaging networks L7/C23 and LS/C26 to the FREQUENCY meter. Since the waveform at X
has a 50-percent duty factor (when fin = 100 kHz), its average value is half-way between minimum and maximum
voltages; and this is the approximate voltage developed across C 23. The average value at Y is the same as at
X, since the waveform at Y also has a 50-percent duty factor; so the voltage across C23 is the same as that
across C26. Thus there is no potential difference across the FREQUENCY meter, and therefore no meter
deflection.
Next assume that fin has decreased, as would be the case if the frequency of the monitored signal were low.
The one-shot will now be trig'gered less frequently, as shown in Figure 4-11. As a result, the voltag'e at X will
now be high more than 50 percent of the time, and the average voltage across C23 will increase according'ly. On
the other hand, the voltage at Y is low more than 50 percent of the time, so its average voltag'e drops by the
same amount that the voltage at X rises. Thus a potential difference is produced across the meter, with the
more positive voltage being at C 23; and this causes the meter to deflect toward the - side of its scale.
In the third case, where fin is high, the average voltages produced are such that the voltage at C26 is more
positive than that at C 23, causing the meter to deflect toward the + side of its scale.
Two controls are provided to adjust the zero reading of the FREQUENCY meter. One (R44) is an internal
coarse control; the other (FP-R1) is the front-panel CAL. control. Adjustment of these controls is covered in
the Maintenance and Operating Instructions sections, respectively.
The schematic diagram of the FREQUENCY meter board is given in Figure 6-22. For most settings of the
frequency selector switches, the La frequency is 10 MHz lower than the dialed-in frequency. When this is true,
a relay is deenergized and its contacts are as shown in the schematic diagram. Under these conditions, the
input from the Q9 side of the frequency-error detector is applied to the positive terminal of the meter through
range switch FP-SW7 and the selected resistors; and the input from the Q6 side is applied to the negative
terminal of the meter.
However, when the 1st-digit frequency selector switch is in position 0 or 1 while the 2nd-digit switch is in
position 2 or 3, and also when the 1st-digit switch is in position <I while the 2nd-digit switch is in position 5 or
6, the La frequency is 10 MHz higher than the dialed-in frequency. For these combinations of 1st-digit and 2nd
digit switch settings, the relay is energized and its contacts reverse the connections to the meter so that a high
input frequency will still produce a positive meter reading.
In the FM, CW, and CAL. positions of the function switch, the input to the meter is through specific range
resistors to provide fixed ranges of ±5 kHz, ±1.5 kHz, and ±1.5 kHz, respectively. Two diodes provide meter
protection in the event of overdrive.

Figure 4-11. FREQUENCY Meter Bridge Circuit, Simplified Schematic Diagram and Waveforms
4-24
The voltage at pin 9 of the FREQUENCY meter board connector, which is proportional to LF. signal fre
quency error, is also fed to the Modulator to control the frequency of the 10-MHz FM oscillator.
4.3.3 Audio Circuits. The waveforms in Figure 4-11 show how the voltage on the two capacitors changes when
the frequency being measured is not exactly 100 kHz. 1£ the incoming signal is frequency-modulated, the duty
cycle of the pulse trains at X and Y will vary at the modulation rate, causing a variation of average voltage at
X and Y at the modulation rate. This does not affect the meter reading because of the filtering effect of L7, L8,
C23, and C26.
As shown in Figures 4-10 and 6-16, the varying voltage (modulation) at the output of the low-pass filter is
fed to the Deviation Meter or Oscilloscope, whichever is plugged in. The audio signal is also fed through an
emitter follower, QlO, to the speaker volume control.
4.3.4 Signal-Level Detector. The plug-in Broadband Mixer and Preselectors contain a squelch detector which
produces a dc output proportional to the strength of the received signal at the output of the 1st LF. amplifier.
This dc signal is applied to a Schmitt Trigg'er (see Figures 4-10 and 6-16), which fires when the signal level at
the output of the 1st LF. amplifier is approximately 60 millivolts. When the Schmitt Trigger fires, it turns on
switching transistor Q8, which enables the frequency-error detector. When Q8 is turned on, it also lights SIG
NAL LEVEL lamp FP-DSI to indicate that the signal level is high enough for reliable measurement. The Schmitt
Trigger remains fired and Q8 remains on as long as the signal amplitude remains above the critical level.
4.4 Signal Generating Circuits
Signals in the ranges of 20 to 80 MHz, 120 to 180 MHz, and 450 to 512 MHz are generated by miXing a CW or
FM 10-MHz signal with a signal from the Frequency Synthesizer. The Frequency Synthesizer output is deter
mined by the settings of the frequency selector switches, as described in Section 4.1 and illustrated in the over
all block diagram, Figure 4-1. The circuits involved in signal generation - the 10-MHz Modulator and the
Signal Generator Mixer - are described in the following sections.
4.4.1 Modulator (CH-A14). The purpose of the modulator is to frequency-modulate the 10-MHz input to the
Signal Generator Mixer when the CE-3 is operating in the FM signal generation mode. The modulating signal
can be either a I-kHz input from the Frequency Synthesizer or an external signal in the range of 60 Hz to 20 kHz.
Figure 6-17 is the Modulator schematic diagram.
The 10-MHz FM signal is generated by a voltage-controlled oscillator, Q3. Its frequency is set to 10 MHz,
as indicated by zero error on the FREQUENCY meter, by the FM CAL. control, R4, located on the front panel
concentrically with the DEV. ADJ. control. The FM CAL. control adjusts the voltage applied to the Varicap in
the frequency-determining portion of the oscillator circuit. Once set to exactly 10 MHz, the oscillator frequency
is controlled by the AFC voltage from the frequency-error detector circuit in CH-A20.
The internal I-kHz modulating signal from the Reference Divider in the Frequency Synthesizer is amplified
by ICl, which is turned on when the FM MOD. switch is in the INT. position; the signal is then fed to the DEV.
ADJ. potentiometer. When the FM MOD. switch is in the EXT. position, the external signal applied through the
front-panel EXT. connector is fed to the DEV. ADJ. potentiometer. This potentiometer adjusts the modulating
signal level to the Varicap in the FM oscillator, and thus adjusts the amount of deviation of the generated 10-MHz
signal. The output of the FM oscillator is amplified by Q4, Q5, and Q6.
When the front-panel function switch is in the CW or CAL. positions, FM oscillator Q3 and amplifier Q4 are
turned off by removing their 20-volt supply, and the 10-MHz harmonic generator in the Frequency Synthesizer is
turned on to supply an unmodulated lO-MHz signal through Q5 and Q6 to the Modulator output.
4-25
In the FM and CW signal generation modes, the Modulator output is fed through the signal generation attenu
ator to the Signal Generator Mixer. The attenuator is calibrated in terms of voltage level at the output of a 20-db
pad connected to the SIGNAL GEN. OUT connector. For a given 10-MHz input, slightly different output voltages
are produced by the Signal Generator Mixer for the three different FM bands. Therefore, the Modulator output
level must be slightly different for each of these bands so that the attenuator readings will be accurate. This is
accomplished by using a different bias on Q6 for each position of the first-digit frequency selector switch. The
biases are individually set by variable resistors R34, R36, and R38 in conjunction with factory-selected resistors
R35, R37, and R39.
The tuned circuit of the 10-l\1Hz FM oscillator (Q3) consists of C19, C20, L2, C2l, C22, and Varicap CRI in
series with C17. The capacitance of the Varicap varies with the voltage applied across it. This voltage is from
two sources: the AFC voltage from the frequency-error detector, as adjusted by the FM CAL. control; and the
modulating voltage from the Frequency Synthesizer or an external source through the DEV. ADJ. control.
Transistors Ql and Q2 comprise an audio amplifier for feeding the I-kHz signal from the Frequency Synthe
sizer to the 1 KHz OUT connector when the FM MOD. switch is in the INT. position.
4.4.2 Signal Generator Mixer (CH-A 7). The purpose of the Signal Generator Mixer is to mix the Frequency
Synthesizer output with 10 MHz to produce an output whose frequency is indicated by the frequency selector.
This is necessary because the Frequency Synthesizer output is displaced 10 MHz from the frequency selector
reading in order to produce a 10-MHz LF. for the frequency measurement mode of operation.
As shown in the schematic diagram, Figure 6-18, the Signal Generator Mixer is an untuned crystal type. In
the CW signal generation mode, the 10-MHz input is from the Frequency Synthesizer via the calibrated attenuator.
In the FM signal generation mode, the 10-MHz input is from the Modulator via the attenuator.
4.5 Power Supplies (CH-A19, RP-Al)
The CE-3 contains three power supplies, providing regulated outputs of +5 volts, +20 volts, and -12 volts.
Figures 6-19 and 6-20 are the schematic diagrams. Three separate windings on the power transformer supply
ac power to the three bridge rectifiers (Figure 6-19). The output of each rectifier is fused at 1 ampere, filtered
by a single capacitor, and fed to a regulator. In addition, the unregulated l2-volt output is used to operate the
coaxial relay.
The power transformer is located at the right rear of the cabinet, and the rectifiers and filter capacitors
are on board RP-A1 at the left rear of the cabinet. All three regulators are on plug-in board CH-A19.
4.5.1 +5V Regulator. This is a conventional series regulator (see Figure 6-20). The sampling element consists
of R14, R16, and voltage adjust potentiometer R15. Q9 is the comparison element and Zener diode CR4 is the
reference element; voltage for the reference element is supplied by the +20V regulator. Q7, compound-connected
with CH-Q2, is a current amplifier to provide enough base current to CH-Q2 to maintain the required load
current.
The circuit consisting of Q8, CR3, and R 11 provides overload protection. If the load current increases above
about 1.5 amperes, the voltage drop across R11 will cause Q8 to saturate, reducing the current at the base of Q7
to a value which will limit the current through CH-Q2 to a safe value. The Zener diode across the regulator out
put provides overvoltage protection.
4.5.2 +20V and -12V Regulators. The circuits of these two regulators (Figure 6-20) are identical except for
component values; therefore, only the +20V circuit will be described. This is a conventional series regulator.
The sampling circuit consists of R8, R 10, and voltage adjust potentiometer R9. The comparison element consists
4-26
of the differential amplifier, Q5 and Q6, plus dc amplifier Q4; and the reference element is CR2. The dc ampli
fier, Ql, and the series regulator transistor, CH-Ql, are compound-connected as described for the +5V regula
tor. Field-effect transistor Q2 serves as a constant-current source. The overload protection circuit consisting
of Q3, R3, and CR 1 operates in the same way as the overload protection circuit in the +5V regulator.
4.6 Miscellaneous Circuits
4.6.1 Decimal and MHz/kHz/Hz Light-Switching Circuits (CH-A5). This board turns on the proper decimal
light in the frequency display, and also turns on either the MHz, kHz, or Hz light to indicate the units in which
the frequency is being displayed.
Figure 6-21 is the schematic diagram of CH-A5, and Figure 4-12 is a functional diagram showing inter
connections with switches and lights. An 8.5-vac input from transformer T 1 across TP6 and TP9 is rectified
by CRI to produce 12 volts dc across Cl. Assume first that the Model 308 Decade Frequency Divider is not
plugged into the CE-3. The base-emitter junction of Ql will be forward biased, since the base does not have a
connection to the negative terminal of the 12-volt power supply; therefore, Ql saturates, switching on Q2, which
turns on the MHz light in its collector circuit. Since Q2 is on, it provides a connection to the negative terminal
of the power supply for the wiper of switch SWl. If 1st-digit switch SWI is in the 0, 1, or 4 position, the 3rd
decimal light will have a negative return and so will come on. If the 1st-digit switch is in the I.F. position, the
wiper of the LF. FREQUENCIES range switch will have a negative return. If the range switch is in the 0-4 MHz
position, the 2nd decimal light will come on; if the switch is in the 4-40 MHz position, the 3rd decimal light will
come on.
When the Model 308 Decade Frequency Divider is plugged in, the base of Ql is returned to the negative
terminal of the 12-volt power supply; thus, Ql and therefore Q2 will be turned off, and there will be no connec
tion to power-supply negative at TP4. Thus, the MHz light will be off, and the 1st-digit and I.F. FREQUENCIES
range switches will be ineffective. Selection of both the decimal and unit lights will be made by the switch on
the Model 308.
Operation of these circuits are summarized in the following tabulation:

4.6.2 Display-Light Flasher. If a frequency not covered by the CE-3 is accidentally dialed-in, the frequency
display lights flash on and off to warn the operator. The following tabulation gives the combinations of 1st and
2nd digits which will result in a flashing display.

The circuit to produce the flashing is shown in the schematic diagram, Figure 6-22, and in simplified form
below. The 1st-digit and 2nd-digit frequency selector switches are wired around the light flasher in such a way
that the flasher is shorted out for all correct combinations of 1st and 2nd digits. Incorrect combinations, how
ever, unshort the flasher and caUSe the display lights to flash.

SECTION 5
MAINTENANCE
5.1 General
The Maintenance section is divided into two major subsections - calibration adjustments and trouble
shooting. If alignment or adjustments other than those described in Section 5.2 are required, it is recommended
that the instrument or subassembly be returned to the factory in accordance with the instructions printed on the
last page of this manual.
Detailed instructions for placing the CE-3 in a particular mode of operation are not included in Section 5.2
and 5.3 because they are given in Section 3. The instrument should be warmed up for at least 30 minutes before
any calibration is attempted. Covers must be removed to make most of the tests and adjustments described.
5.1.1 Access. Components in the top part of the instrument can be reached by removing the two L-shaped side
covers. Each cover is secured to the cabinet by six screws. The speaker must be disconnected before the
right-hand cover can be completely removed.
The VCO and all of the plug-in circuit boards become accessible by removing the bottom cover. To do this,
stand the instrument on its rear panel, and remove the eight screws holding the bottom cover to the cabinet.
5.1.2 Subassembly Removal. A board extractor and an extender board are shipped with the instrument in a
plastic bag. TO REMOVE A BOARD AFTER THE BOTTOM COVER HAS BEEN TAKEN OFF, FIRST MAKE SURE
POWER HAS BEEN DISCONNECTED FROM THE BOARDS BY CHECKING TO SEE THAT THE SPEAKER VOL
UME SWITCH IS IN THE OFF POSITION. Then hook the extractor into the holes in the board, and pull out the
board. If the board is to be operated outside the cabinet so that measurements or adjustments can be made on it
while it is energized, plug the extender board into the socket from which the board has been removed, and then
plug the board into the extender.
If the VCO box must be removed, first unplug the four coaxial cables, then loosen the two screws in the
U-joint so that the U-joint will remain on the VCO rather than on the main shaft. Remove the three screws
holding the VCO box to the chassis, and slide the VCO box off the shaft. When reinstalling the VCO box, be sure
that the index mark on the U-joint points to the same number on the VCO box that the 3rd-digit knob indicates on
the front panel.
The model 302 Deviation Meter and the Model 301 Oscilloscope, which plug into the left-hand side of the
CE-3, are released for removal by turning a small knob behind the plug-ins on the rear panel of the CE-3. The
Model 303 Broadband Mixer and the Models 304, 305, and 306 Preselectors, which plug into the right-hand side
of the CE-3, are released for removal by turning a small knob on the front panel of the plug-ins.
5.1.3 Fuses. There are three regulated power supplies within the basic CE-3: +5 volts, +20 volts, and -12
volts. Each of the supplies has a fuse located inside the CE-3 cabinet on a printed-circuit board. The board is
mounted on the rear panel behind the Deviation Meter or Oscilloscope plug-in.
The +20-volt fuse is near the outside of the board, the -12-volt fuse is in the center of the board, and the
+5-volt fuse is toward the center of the instrument. If one of these fuses blows, the resistance between the
regulator output terminal and ground should be measured to make sure that there is not a short circuit. Table
5-1 gives the approximate resistance to chassis ground for each supply (or, in the case of the plug-ins, for the
load across each supply).
A separate ac fuse, located on the rear panel, can be replaced without removing the CE-3 side covers. Also,
a .2 amp slo-blo fuse for 115 vac input to the scope plug-in is mounted near the back connector in the scope
plug-in compartment of the CE-3.

NOTE
The regulated power supplies are set to within 0.5% of rated
output voltage at the factory and should not be adjusted un
less a voltmeter having an accuracy of at least 1% is used.
a. Measure the -12-volt supply voltage (to chassis ground) at pin 14 on the female connector for the Broad
band Mixer and Preselector plug-ins (orange wire). Adjust potentiometer R25 to give a reading of exactly 12.0
volts.
b. Measure the +20-volt supply voltage (to chassis ground) at pin 17 of the female connector for the Broad
band Mixer and Preselector plug-ins (red wire). Adjust potentiometer R9 for exactly 20.0 volts.
c. Measure the +5-volt supply voltage (to chassis ground) at pin 15 of the female connector for the Broad
band Mixer and Preselector plug-ins (green wire). Adjust potentiometer R15 for exactly 5.0 volts.
5.2.2 Master Oscillator Calibration.
Test Equipment Required:
Method 1: Sensitive receiver capable of receiving WWV on 10 MHz. Receiver should be equipped with
a signal strength meter.
Method 2: A frequency counter with a crystal time base accuracy known to be at least 1 part in 107.
Method 1: Although this relatively simple technique is familiar to most technical people, a few of the basic
requirements for successful use of the WWV Izero-beat technique are covered here.
It should be understood that the crystal oven of each CE-3 has been aged for over a month before shipment,
during which time its stability has been carefully watched and recorded. Based upon this fact, we rate the in
strument to have and keep 0.000075% frequency accuracy or better for at least six months. It is suggested,
however, that a check for frequency accuracy be made at least annually.
Technically speaking, the 0.000075% specification is not difficult with tOday's state of the art; however, any
adjustment of the glass piston capacitor trimmer, which allows shifting of the oscillator frequency, should be
carefully done. Keep in mind that the best time of the day for tests is during the hours which would be midday
between the WWV transmitter (currently located in Colorado) and the user's location. This timing avoids some
of the slight Doppler effect which might appear if sunrise or sunset occurred at either the user's location or at
the transmitter location.
When tuning the receiver, be certain to identify the station by its voice announcements. It is assumed that
you will pick a time when reception will be clear and relatively noise-free. Your receiver and the location and
orientation of the antenna will also play an important part.
As mentioned in this manual previously, it is advisable to keep the CE-3 plugged into a 115-volt ac source
at all times to ensure that the crystal and oven are at their correct temperature. If the unit has not been plugged
into ac power, do so and let the instrument operate for 30 minutes or more before starting the test.
For the test itself, while monitoring the WWV station, switch the CE-3 to the CW signal generating position.
In this position, 10 MHz will be present at the SIGNAL GEN. OUT connector. Using a BNC connector at this
point, bring the "hot" lead near the receiver antenna terminals. Connect a grounding lead between the CE-3 and
the receiver. It is recommended that the insulated "hot" lead be wrapped around the receiver antenna terminals
5-7
at least once to give a few pFof coupling, which is normally adequate to get enough sig:1al from the CE-3 to the
receiver for making the test.
Advance the CE-3 SIGNAL GEN. ATTEN. controls while watching the signal strength meter. The meter
will rise as the control is advanced and the WWV signal will be "wiped out" if the control is advanced too far.
Set the control where it appears that neither signal is stronger than the other. By watching the signal strength
meter, you may observe a definite periodic beat which will indicate any error in the Master Oscillator frequency.
At this point, recognize that 0.000075% maximum allowable frequency error would amount to 7.5 Hz at 10 MHz.
If correction of the CE-3 oscillator is required, select a period of the WWV transmission when no tones or voice
announcements are heard. Use the following procedure.
On the right side near the rear of the instrument (as viewed from the front panel), you will see the crystal
oven. Just below the oven and projecting forward is the threaded screw of the crystal trimmer capacitor. Using
a slotted screwdriver (while observing the signal strength meter), adjust this s crew until the periodic swing of
the signal strength meter comes to a stop. By swinging through zero beat several times, the proper position for
the trimmer becomes apparent.
Method 2: Remove the cable marked D from the input to the 330-MHz harmonic generation container, and
connect the cable to the input of a frequency counter. It is imperative that the time base oscillator in the counter
be accurate to 1 part in 107 . The counter should indicate a frequency of 33.0 MHz. If the error indicated
by the counter exceeds 3 parts in 106, an oven or crystal malfunction should be suspected. The frequency of the
M8.ster Oscillator can be adjusted as described in the last paragraph of Method 1 above.
5.2.3 FREQUENCY Meter Range Calibration. This method uses the instrument's I.F. output to calibrate the
meter. It will provide sufficient accuracy if the CE-3 Master Oscillator has been calibrated. Before starting
the procedure, and with power off, adjust the mechanical zero of the FREQUENCY meter, if necessary.
a. Set the first-digit switch to I.F. and the function switch to CAL.
b. Zero the FREQUENCY meter with the CAL. red knob.
c. Turn the function switch to FREQ.-DEV. MEASURE.
d. Adjust the CE-3 for an I.F. output of 9.999 MHz.
e. Connect a cable from the I.F. FREQUENCIES OUTPUT connector to the ANT. connector.
f. Turn the I.F. LEVEL control fully clockwise.
g. Set the FREQUENCY meter range switch to ± 1.5 kHz.
h. The meter should read minus (.. ) 1.0 kHz on the lower scale. If it does not, adjust potentiometer R6 on
the FREQUENCY meter printed-circuit board (FP-A 1) located on the rear of the FREQUENCY meter.
i. Set the meter range switch to ± 5 kHz.
j. Dial-in 9.995 MHz. The meter should indicate an error of minus (-) 5.0 kHz on the upper scale. If it
does not, adjust potentiometer R4 on the printed-circuit board.
k. Set the meter range switch to ±15 kHz, and dial-in 9.985 MHz. If the indicated reading is not minus (-)
15 kHz, adjust potentiometer R2 on the printed-circuit board.
1. Meter tracking and discriminator linearity can be checked on the ±1.5, ±5, and ±15 kHz ranges by
dialing-in 10.001, 10.005, and 10.015 MHz, respectively.
5-8
5.2.4 Signal Generation Output Levels.
Test Equipment Required: RF Generator (HP 608 or equivalent)
Receiver capable of operating at the frequencies to be checked and having a 50-ohm input impedance.
The output levels are calibrated by the signal substitution method, in which a signal from a calibrated
source is fed into a metered receiver and the meter reading noted. The CE-3 is then substituted for the cali
brated source and the output of the CE-3 is adjusted until the meter reads the same as before. The receiver
should be metered at a point where saturation is least likely to occur (e.g., the first or second LF. stage) and
the RF input signal should be low level (preferably 0.5 to 1.0 microvolt).
a. Select a frequency at which the adjustment is to be made. This frequency must be within the capabili
ties of the external receiver, the external signal generator, and the CE -3.
b. Set the signal generator to this frequency by monitoring it on the CE-3. (When using frequencies higher
than 100 MHz the signal generator must be tuned very slowly because the bandwidth of the CE-3 is quite narrow
and there is some delay in receiver "turn-on;" the higher the signal generator output level, the less the delay).
c. Set the sig'nal generator output to 0.5 microvolt.
d. Feed the signal generator output into the receiver and note the receiver meter reading. (Be cautious
of signal generator frequency drift.)
e. Adjust the CE-3 to generate a CW signal on the receiver frequency at a 0.5-microvolt level.
f. Disconnect the signal generator from the receiver, and connect the output of the CE-3 to the receivel'
through the 20-db pad furnished with the CE-3.
g. If the receiver meter does not read the same as in step d, adjust the appropriate control on the Modu
lator board in the CE-3. The control to adjust depends on the frequency band. The cnntrols are marked on the
right side of the chassis near the front panel (see Figure 5-1). Typical calibration frequencies are as follows:
Nominal Frequency Frequency Band for Calibration
20 - 80 MHz 35 MHz 120 - 180 MHz 155 MHz 450 - 512 MHz 460 MHz
5.2.5 20-db Fixed AttenuatoI'. A 20-db pad is shipped in the front door of the CE-3. The CE-3 attenuators are
calibrated in terms of signal voltage at the output of the 20-db pad. Therefore, the pad must always be used
when it is desired to read signal output levels directly from the attenuators. The purpose of the pad is to pro
tect the instrument against accidental keying of a transmitter directly into the CE-3. If a transmitter is keyed,
it will normally burn out the RF fuse in the pad; depending on power, it could also burn out one or more of the
resistors in the pad.
It is essential that the pad attenuate the signal precisely 20 db. If there is any doubt about the condition of
the pad, check it as follows: Feed a I-microvolt signal directly from the signal generator into the receiver, and
note the receiver meter reading; then feed a 10-microvolt signal through the pad into the receiver. The two
receiver meter reading's should be within 0.5 db.
Repair of the pad is quite simple. Remove the single screw and slide the cover off the pad. A schematic
diagram inside the pad shows values of the components. The resistors are standard 5% values available from
most electronic parts stores. The fuse is a special RF fuse (Bussman ~ nd may be purchased from
a parts house or is available from Cushman Electronics. The Cushman part number for a package of 10 fuses is
7040-0018. The price is $8.00 for a package.
5-9
5.2.6 Modulator Center Frequency Adjustment.
a. Adjust the CE-3 for operation in the FM mode.
b. Mechanically center the FM CAL. control with the DEV. ADJ. control fully CCW.
c. Adjust the FM oscillator coil on the 10 MHz Modulator board (see Fig'ure 5-4) for a zero reading on
the FREQUENCY meter.
5.3 Troubleshooting
Table 5-2 is a troubleshooting chart which should, in most cases, enable the service man to isolate the
cause of a malfunction to a particular subassembly or (in the case of the VCO phase-lock loop) to a few sub
assemblies. If the symptoms point to a malfunction on a particular printed-circuit board, the most practical
procedure is to replace the board with one known to be good. If the trouble can be isolated only to a group of
boards, the suspected boards should be tried, one at a time, in an operating CE-3, if such is available. Field
repair of printed-circuit boards, particularly those containing integrated circuits, is not recommended. Boards
suspected of malfunctioning should be returned to the factory for inspection and repair in accordance with the
instructions printed on the last page of this manual.
When a malfunction develops, there is usually some external evidence, such as the failure of a panel meter
or lamp to indicate, or a lack of signal output. Such troubles are listed in the left-hand column of Table 5-2.
If one of the checks recommended for the trouble results in an abnormal indication, check the subassembly
listed in the "Refer to" column.
As an example of the use of Table 5-2, assume that the CE-3 has been working OK in the frequency
measurement mode, but when the function switch is changed to one of the SIG. GEN. positions, no signal is
obtained at the output of the 20-db pad on the end of the test cable. Table 5-2 gives three checks for this mal
function. Assume that the fuse in the pad is checked with an ohmmeter and found to be OK. Then the output of
the coaxial cable from the coaxial relay to the Signal Generator Mixer is checked and found to be zero. Since
the CE-3 operates satisfactorily in the frequency-measurement mode, the Frequency Synthesizer output is
apparently OK; so the trouble is probably in the coaxial relay or in the cable from the relay to the Signal Gen
erator MiJ<:er. The signal voltage at the bottom connector of the coaxial relay is checked and found to be 63 mv.
Therefore, the trouble must be in the connecting cable.
If the observed symptoms do not fit a "trouble" described in the first column of Table 5-2, note what hap
pens when the function switch and frequency selector switches are rotated to different positions. It should then
be possible to match the symptoms thus obtained with one of the troubles listed.
Since the signal levels at the input to the Signal Generator Mixer and at the output of the Frequency Synthe
sizer may give important clues to the source of a trouble, procedures for measuring these levels are given in
Sections 5.3.1 and 5.3.2.
The following test equipment is required for troubleshooting the CE-3:
DC voltohmmeter, 20,000 ohms-per-volt or higher sensitivity, 1% accuracy (Simpson Model 270 or equivalent)
RF voltmeter, 1GHz (Boonton Model 91DA or equivalent)
5.3.1 Signal Generator Mixer Input Levels. As shown in the overall block diagram, Figure 4-1, two inputs are
supplied to the Signal Generator Mixer - a 10 MHz signal from the Frequency Synthesizer through the attenua
tor, and a signal in the range of 460 to 502 MHz from the Synthesizer through the coaxial relay. The input from
5-10
I
the coaxial relay may also contain either a 330-MHz or a 430-MHz signal, depending on the setting of the 1st
digit frequency selector switch (see Figure 4-2).
To check the level of the 10-MHz input, proceed as follows:
a. Set the SIGNAL GEN. ATTEN. controls for maximum output (range switch to X100 and MICROVOLTS
control fully clockwise).
b. Turn the function switch to CW.
c. Disconnect the coaxial cable from the top connector of the Signal Generator Mixer (see Figure 5-1).
d. With an RF voltmeter terminated in 50 ohms, measure the voltage at the cable output. It should be
approximately 50 millivolts.
The level of the input from the coaxial relay is checked as follows:
a. Turn the function switch to CW.
b. Disconnect the coaxial cable from the rear connector of the Signal Generator Mixer (see Figure 5-1).
c. With an RF voltmeter terminated in 50 ohms, measure the voltage at the cable output. It should be
between 50 and 75 millivolts.
5.3.2 Frequency Synthesizer Output Level. The Frequency Synthesizer output to the RF plug-in (Broadband
Mixer or one of the Preselectors) is a signal in the range of 460 to 502 MHz. It may also contain a signal having
a fixed frequency of 330 MHz or 430 MHZ, depending on the setting of the 1st-digit frequency selector switch.
To measure the level at the coaxial relay, proceed as follows:
a. Disconnect the coaxial cable between the coaxial relay and the RF plug-in at the BNC connector on the
top of the coaxial relay (see Figure 5-1).
b. Turn the function switch to the FREQ.-DEV. MEASURE position.
c. Turn the 1st-digit switch to "4".
d. With an RF voltmeter terminated in 50 ohms, measure the voltage at the BNC connector on top of the
coaxial relay. It should be between 50 and 75 millivolts.
e. Disconnect the "E" cable from the 460-502 MHz Filter (see Figure 5-2).
f. Set the 1st-digit switch to "0" or "1".
g. With an RF voltmeter terminated in 50 ohms, check the voltage at the top connector of the coaxial
relay. It should be between 30 and 75 millivolts.
5.3.3 VCO Phase Lock. In normal operation, the VCO is phase-locked with the Reference Divider by means of
the closed loop consisting of the VCO, the -:- N Counter, the Sample and Hold circuits, and the Phase Detector
(see Figure 4-2). If the VCO loses lock, as evidenced by the UNLOCKED light coming on, the most probable
cause is a malfunctioning of one of these boards within the loop, or a malfunctioning Master Oscillator board.
The only practical method of troubleshooting a loss of phase lock is to substitute these boards, one at a time,
into a working CE-3.
An out-of-lock condition could also be caused by mechanical misalignment of the VCO switch with the 3rd
digit front-panel switch. Alignment can be checked by turning the 3rd-digit switch to "0" and observing whether
the mark on the VCO shaft is in line with the mark on the retaining nut.
