Factory Acceptance Test Procedure

Transmitter Output Power TestTest Type: Station test

Test Objective: To confirm that the output power of MSTU is within thelimit

Specifications:

TX output power: +29 dBm or +32 dBm0.5 dB (ATPC: HIGH), +19 dBmor +22 dBm0.5 dB (ATPC: LOW)(+29/+19 dBm: Standard power model, +32/+22 dBm: High power model)+ 29 dBm (ATPC: HIGH)/ +19 dBm (ATPC: LOW) for 11 GHz+27 dBm (ATPC: HIGH)/ +17 dBm (ATPC: LOW) for 13 GHzMeasured at TX port on MSTU with modulated power.

Test instruments required:Power meter with sensor (EPM-442A+8481A or equivalent)Fixed attenuator (30 dB) or equivalent.PC (for WebLT)

Test set-up: Set up the test circuit as shown in Figure 1-1

TX Output Power Measurement Procedure:

1. Turn off the circuit power breaker on MSTU.

2. Remove the TX OUT cable.

3. Connect power meter to the SMA connector marked with TX.If the maximum range of the power meter is less than the rated output power levelof MSTU, insert fixed and calibrated attenuator between the TX output and thepower meter.

4. Turn on the circuit power breaker on MSTU.

5. Set the TX output power to HIGH.

6. Read the power meter indication.

7. Set the TX output power to LOW.

8. Read the power meter indication.

NOTE:

TX output power is specified at the MSTU output port, and themeasured value at the MSTU Adapter should be converted by thefollowing equation.TX output power = Measured value + MSTU Adapter loss

Transmitter SpuriousTest Type: Station test

Test Objective: To confirm that the TX output spurious is within thelimit.

Specifications:

Test instruments Required:Spectrum analyzer (HP8565F or equivalent)Fixed attenuator (30 dB)PC (for WebLT)

Test set-up: Set up the test circuit as shown in Figure 1-2

Frequency Band Frequency Range Specification

Out of Band 30 MHz - 21.2 GHz -60 dBm

21.2 GHz - 40 GHz -30 dBm

In band1

1. ft +/- 100 MHz is not included. (ft is the MSTU transmission frequency.)

TX side half band -60 dBm

RX side half band -90 dBm2

2. This specification is described in the current TR6500 data format whilethis value is not specified in the latest R&TTE requirement. This value isnot measured in the actual TR6500 factory testing at present. However,this value is guaranteed at the design verification level.

IMN-907006-E02 REV 03 APRIL 2010 9


Test Procedure

1. Turn off all circuit power breakers on MSTU.

2. Connect the spectrum analyzer to the duplexer (DUP) output port through the30-dB high power fixed RF attenuator.

3. Turn on the circuit power breaker of MSTU to be measured.

4. Set the transmitter output signal to CW (Carrier Wave) to stop modulation withWebLT.

5. Set the RF level of the Reference Point A to 0dBm with the variable attenuator.

6. Set the 0dBm reference line to the upper part of the spectrum analyzer.

7. Check the level of spurious displayed on the screen of the spectrum analyzer.

8. Restore the connections.

Test Procedure

1. Preparation for measurement

a. Warm up the frequency counter at least 30 minutes before measurement.

b. The BAND SELECT SW on the frequency counter shall be set to theappropriate RF frequency range.

2. Set up the test circuit as shown in Figure 1-4.

3. Record the Transmit Local frequency and calculate its tolerance using the followingformula.Tolerance (kHz) = (Measured frequency - Specified TX LO frequency)

4. Compare the results with the following tables.

Test Procedure


2. Provisioning: IS (In-Service) for all units

3. Calibrate the RF variable attenuator (considering loss of adapter) so as to set theRSL.

NOTE:

RX receiving power is specified at the MSTU input port, and themeasured value should be converted by the MSTU adaptor loss.Refer to Table 1-2for the MSTU adaptor loss.

4. Measure the BER and confirm that the measured BER is met to the specifications.

5. In the case of the measurement of the Protection channel, turn off all circuitbreakers on the Main channels MSTU in order to switch the STM-1 signal path tothe protection channel.

6. In the case of the measurement of the Main channel, turn off the circuit breaker onthe Protection channels MSTU in order to prevent an unexpected switchingoperation.
