Chapter 1General Information

IntroductionThis chapter provides a description, performance specifications, optional accessories, pre-ventive maintenance, and calibration requirements for the Site Master model S114BQ.Throughout this manual, the term Site Master will refer only to the model S114BQ.

Model Frequency RangeS114BQ 2 to 1000 MHz, 100 kHz to 1200 MHz Spectrum Analysis

DescriptionThe Site Master is a sythesizer-based hand held SWR/RL (standing wave ratio/return loss),Distance-To- Fault (DTF) and spectrum analysis measurement instrument. The S114BQhas a keypad to enter data and a liquid crystal display (LCD) to provide graphic indicationsof SWR or RL over the selected frequency range and selected distance. The Site Master iscapable of up to 2.5 hours of continuous operation from a fully charged field-replaceablebattery and can be operated from a 12.5 dc source. Built-in energy conservation featurescan be used to extend battery life over an eight-hour work day.

The Site Master is designed for measuring SWR, return loss, or cable insertion loss, locat-ing faulty RF components in antenna systems, and spectrum analysis. Power monitoring isavailable as an option. The displayed trace can be scaled or enhanced with frequency mark-ers or a limit line. A menu option provides for an audible “beep” when the limit value is ex-ceeded. To permit use in low-light environments, the LCD can be back lit using a frontpanel key.

Standard AccessoriesThe Software Tools PC-based software program provides a database record for storingmeasurement data. Site Master Software Tools can also convert the Site Master display to aMicrosoft Windows� 95/98/NT workstation graphic. Measurements stored in the Site Mas-ter internal memory can be downloaded to the PC using the included null-modem serial ca-ble. Once stored, the graphic trace can be displayed, scaled, or enhanced with markers andlimit lines. Historical graphs can be overlaid with current data, and underlying data can beextracted and used in spreadsheets or for other analytical tasks.

The Site Master Software Tools program also performs DTF (Distance To Fault) and FaultLocation.

* ±2 ppm/�°C from 25°C** Fault location is accomplished by inverse Fourier Transformation of data taken with the Site Master. Resolution andmaximum range depend on the number of frequency data points, frequency sweep range and relative propagation veloc-ity of the cable being tested.*** Immunity measurement is made in CW mode with incoming interfering signal exactly at the same frequency (worstcase situation). Typical immunity is better when swept frequency is used.

Preventive MaintenanceSite Master preventive maintenance consists of cleaning the unit and inspecting and clean-ing the RF connectors on the instrument and all accessories.

Clean the Site Master with a soft, lint-free cloth dampened with water or water and a mildcleaning solution.

CAUTION: To avoid damaging the display or case, do not use solvents or abra-sive cleaners.

Clean the RF connectors and center pins with a cotton swab dampened with denatured alco-hol. Visually inspect the connectors. The fingers of the N (f) connectors and the pins of theN (m) connectors should be unbroken and uniform in appearance. If you are unsure whetherthe connectors are good, gauge the connectors to confirm that the dimensions are correct.

Visually inspect the test port cable(s). The test port cable should be uniform in appearance,not stretched, kinked, dented, or broken.

CalibrationThe Site Master is a field portable unit operating in the rigors of the test environment. AnOpen-Short-Load (OSL) calibration should be performed prior to making a SWR/RL mea-surement in the field. A built-in temperature sensor in the Site Master advises the user, viaan icon located on the right side of the LCD screen, that the internal temperature has ex-ceeded a safety window, and the user is advised to perform another OSL calibration in or-der to maintain the integrity of the measurement.

NOTES:For best calibration results—compensation for all measurement uncertain-ties—ensure that the Open/ Short/Load is at the end of the test port or optionalextension cable; that is, at the same point that you will connect the antenna ordevice to be tested.

For best results, use a phase stable Test Port Extension Cable (see OptionalAccessories). If you use a typical laboratory cable to extend the Site Master testport to the device under test, cable bending subsequent to the OSL calibrationwill cause uncompensated phase reflections inside the cable. Cables which arenot phase stable may cause measurement errors that become more pro-nounced as the test frequency increases.

For optimum calibration, Anritsu recommends using precision calibration components.

The Site Master S114BQ performs a spectrum analysis calibration during start-up. Spec-trum analysis calibration is not required prior to making a spectrum analysis measurement.

Annual VerificationAnritsu recommends an annual calibration and performance verification of the Site Masterand the OSL calibration components by local Anritsu service centers. Anritsu service cen-ters are listed in Table 1-2 on the following page.

The Site Master itself is self-calibrating, meaning that there are no field-adjustable compo-nents. However, the OSL calibration components are crucial to the integrity of the calibra-tion and therefore, must be verified periodically to ensure performance conformity. This isespecially important if the OSL calibration components have been accidentally dropped orover-torqued.

Chapter 2Getting Started

IntroductionThe Nickel Metal Hydride (NiMH) Battery supplied with the Site Master is shipped in adischarged state. Before using the Site Master, the internal battery must first be charged forthree hours, either in the Site Master or in the optional battery charger (Anritsu part num-ber: 2000-1029).

Charging a New BatteryNew batteries normally require three to five charge and discharge cycles before attainingmaximum performance. The NiMH battery supplied with the Site Master has already com-pleted three charge and discharge cycles at the factory and full battery performance shouldbe realized after your first charge.

Charging the Battery in the Site Master

The battery can be charged while still installed in the Site Master.

Step 1. Turn the Site Master off.

Step 2. Connect the AC-DC adapter (Anritsu part number: 40-115) to the Site Mastercharging port.

Step 3. Connect the AC adapter to a 120 VAC or 240 VAC power source as appropriatefor your application.

The green external power indicator on the Site Master will illuminate, indicatingthe presence of external DC power and the battery will begin charging. The indi-cator will remain lit as long as the battery is charging. Once the battery is fullycharged, the battery indicator will turn off. If the battery fails to charge, contactyour nearest Anritsu service center.

Charging the Battery in the Optional Charger

Up to two batteries can be charged simultaneously in the optional battery charger.

Step 1. Remove the NiMH battery from your Site Master and place it in the optionalcharger (Anritsu part number: 2000-1029).

Step 2. Connect the lead from the AC-DC adapter to the charger.

Step 3. Connect the AC-DC adapter to a 120 VAC or 240 VAC power source as appro-priate for your application.

Each battery holder in the optional charger has an LED charging status indicator. The LEDcolor changes as the battery is charged:

Red indicates the battery is chargingGreen indicates the battery is fully chargedYellow indicates the battery is in a waiting state (see below).

2 - 1

2

A yellow light may occur because the battery became too warm during the charge cycle.The charger will allow the battery to cool off before continuing the charge. A yellow lightmay also indicate that the charger is alternating charge to each of the two batteries.

A blinking red light indicates less than 13 VDC is being supplied to the charger stand.Check that the correct AC charger adapter is connected to the charger stand.

If a battery fails to charge, contact your nearest Anritsu Service Center.

You can charge the battery anytime. However, NiMH battery will last longer and performbetter if allowed to completely discharge before recharging. For maximum battery life, it isrecommended that the NiMH battery be completely discharged and recharged once everythree months.

Battery Charge IndicatorWhen the AC-DC adapter is unplugged from the Site Master, the battery indicator symbolwill be continuously displayed at the top left corner of the Site Master display (Figure 2-1).

A totally black bar indicates a fully charged battery. When LOW BATT replaces the bat-tery indicator bar at the top left corner, a couple of minutes of measurement time remains. Ifa flashing LOW BATT is accompanied by an audio beep at the end of each trace, the bat-tery has approximately one minute of useable time remaining.

Chapter 2 Getting Started

Battery Indicator

Figure 2-1. Site Master Battery Indicator

The battery status can also be checked by pressing the SYS key and the STATUS soft key.The Status table will display the remaining battery charge as a percent, as shown below.

Once all the power has drained from the battery, the Site Master display will fade. At thispoint, your Site Master will switch itself off and the battery will need to be recharged.

Discharging the NiMH BatteryThe NiMH battery will last longer and perform better if allowed to completely dischargebefore recharging. For maximum battery life, it is recommended that the NiMH battery becompletely discharged and recharged once every three months.

To discharge the battery, leave the Site Master switched on until the battery is drained. TheSite Master will display a LOW BATT message and an audio warning when the battery be-gins to run low. Allow the battery to fully discharge until the Site Master switches itself off.

NOTE:Do not attempt to discharge the battery by any other means. Never short-circuitthe battery terminals.

Battery LifeIt is normal for NiMH batteries to self-discharge during storage. To minimize battery dis-charge during storage, it is recommended that the battery be removed from the Site Masterif the Site Master is not to be used for a long period of time.

It is normal for NiMH battery to degrade to 80% of original capacity after 12 months ofcontinuous use.

The battery can be charged and discharged 300 to 500 times, but it will eventually wear out.The battery may need to be replaced when the operating time between charging is notice-ably shorter than normal.

Chapter 3Functions and Operations

IntroductionThis chapter provides a brief overview of the Site Master functions and operations, provid-ing the user with a starting point for making basic measurements. For more detailed infor-mation, refer to Chapter 4, Measurements and Chapter 5, Software Tools.

The Site Master is designed specifically for field environments and applications requiringmobility. As such, it is a lightweight, handheld, battery operated unit which can be easilycarried to any location, and is capable of up to 2.5 hours of continuous operation from afully charged battery. Built-in energy conservation features allow battery life to be extendedover an eight-hour workday. The Site Master can also be powered by a 12.5 Vdc externalsource. The external source can be either the Anritsu AC-DC Adapter (P/N 40-115) or 12.5Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items are standard accesso-ries.

Front Panel OverviewThe Site Master menu-driven user interface is easy to use and requires little training. Mode,Frequency, Amplitude and Sweep function keys are located just below the display and areeasily configured for optimum measurements. Selection of one of these keys brings up afunction-specific menu on the right hand side of the display. The softkeys adjacent to thedisplay provide access to the various menu items (See Figure 3-1).

� WINDOW — Opens a menu of FFT windowing types for the DTF calcula-tion. Scroll the menu using the Up/Down arrow key and make a selectionwith the ENTER key.

3-12


NOTE: Using windowing:The theoretical requirement for inverse FFT is for the data to extend from zerofrequency to infinity. Side lobes appear around a discontinuity due to the factthat the spectrum is cut off at a finite frequency. Windowing reduces the sidelobes by smoothing out the sharp transitions at the beginning and end of thefrequency sweep. As the side lobes are reduced the main lobe widens therebyreducing the resolution.

In situations where there may be a small discontinuity close to a large one, sidelobe reduction Windowing should be used cautiously. When distance resolutionis critical Windowing can be reduced. The types of Windowing in order of in-creasing side lobe reduction are: rectangular, nominal side lobe, low side lobe,minimum side lobe. Figures 3-11 thru 3-14, on pages 3-14 and 3-15, are exam-ples of the types of Windowing.

Chapter 4Measurements

IntroductionThis chapter provides a description of the Site Master measurement functions and examplesof frequency domain, distance domain, and spectrum analyzer measurements .

Measurement FunctionsSite Master operation is divided into four measurement modes: frequency domain, distancedomain, spectrum analysis, and power monitor.

� Frequency domain measurements consist of Return Loss (RL), Standing Wave Ratio(SWR), and Cable Loss (CL) made over a selectable frequency range. SWR and RL char-acterize the magnitude of reflections present in a device or transmission line. CL mea-surements display the one-port insertion loss of a transmission line over frequency.

� Distance domain measurements—commonly known as distance-to-fault (DTF)—aremade over a selectable distance range. They include RL or SWR, but they also return in-formation that can help locate discontinuities in a transmission line. CL cannot be meas-ured in the distance domain.

� Spectrum Analysis�Typical measurements include in-band interference, antenna align-ment, and cell coverage. Measurements can be easily made by using the main instrumentfunctions: frequency, span, amplitude and sweep. A full range of marker capabilities suchas peak, center and delta functions are provided for fast, comprehensive measurement ofdisplayed signals. Limit lines are available for creating quick, simple pass/fail measure-ments.

� Power monitor measurements can be either absolute or relative to some base power level,and can be displayed in either dBm or Watts. To allow measurement and display ofpower levels above the unit's specified input, the user may attenuate the signal and enterthe corresponding offset. The offset is added to the measured input power prior to dis-play. Finally, a zero adjust function is provided to allow subtraction of an inherent“noise” level prior to display.

CAUTION: The measurement system MUST be calibrated at the ambient tem-perature prior to making a measurement. You must calibrate when the setupfrequency is changed. Calibrations are stored with each of the setups.

It is recommended that open, short, load calibration be performed on the Site Master priorto measurements. This gives confidence to the operator that the measurement performed isaccurate and system uncertainties have been minimized.

NOTES: For best calibration results–compensation for all measurement systemuncertainties–ensure that the Open/Short/Load is at the end of the test port oroptional extension cable; that is, at the same point as the antenna or device tobe tested will be connected.For best results, use a phase stable Test Port Extension cable. In a typical lab-oratory cable, bending subsequent to the calibration will cause uncompensatedphase reflections inside the cable. Cables that are not phase stable may causemeasurement errors that become more pronounced as the test frequency in-creases.

Performing a Calibration

Step 13. Press the START CAL key. Follow the instructions that appear in the messagearea.

Step 14. Connect the Open, Short, and Load component to the test port and press theENTER key as prompted after connecting each component.

Refer to the “Performing a Calibration” procedure on page 4-4 for detailed cali-bration steps.

NOTES:For best calibration results — compensation for all measurement system uncer-tainties — ensure that the Open/Short/Load is at the end of the test port or op-tional extension cable; that is, at the same point that you will connect theantenna or device to be tested.

For best results, use a phase stable Test Port Extension Cable (see OptionalAccessories). If you use a typical laboratory cable to extend the Anritsu test portto the device-under-test, cable bending subsequent to the Open/Short/Load cal-ibration will cause uncompensated phase reflections inside the cable. Thus, ca-bles which are not phase stable may cause measurement errors that are morepronounced as the test frequency increases.

For optimum calibration, Anritsu recommends using precision calibration com-ponents.
