Description

The Site Master is a hand held SWR/RL (standing wave ratio/return loss), and Distance-ToFault (DTF) measurement instrument that includes a built-in synthesized signal source. All models include a keypad to enter data and a liquid crystal display (LCD) to provide graphic indications of SWR or RL over the selected frequency range and selected distance. The Site Master is capable of up to 2.5 hours of continuous operation from a fully charged field-replaceable battery and can be operated from a 12.5 dc source. Built-in energy conservation features can 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 and locating faulty RF components in antenna systems. Power monitoring is available as an option. Site Master models S114B and S332B include spectrum analysis capability. The displayed trace can be scaled or enhanced with frequency markers or a limit line. A menu option provides for an audible “beep” when the limit value is exceeded. To permit use in low-light environments, the LCD can be back lit using a front panel key.

Standard Accessories

The Software Tools PC-based software program provides a database record for storing measurement data. Site Master Software Tools can also convert the Site Master display to a Microsoft Windowsä 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 and limit lines. Historical graphs can be overlaid with current data, and underlying data can be extracted and used in spreadsheets or for other analytical tasks.

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

Chapter 1 General Information

Preventive Maintenance

Site 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 mild cleaning 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 the N (m) connectors should be unbroken and uniform in appearance. If you are unsure whether the 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.

ESD Precautions

The Site Master, like other high performance instruments, is susceptible to ESD damage. Very often, coaxial cables and antennas build up a static charge, which, if allowed to discharge by connecting to the Site Master, may damage the Site Master input circuitry. Site Master operators should be aware of the potential for ESD damage and take all necessary precautions. Operators should exercise practices outlined within industry standards like JEDEC-625 (EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices, equipment, and practices.

As these apply to the Site Master, it is recommended to dissipate any static charges that may be present before connecting the coaxial cables or antennas to the Site Master. This may be as simple as temporarily attaching a short or load device to the cable or antenna prior to attaching to the Site Master. It is important to remember that the operator may also carry a static charge that can cause damage. Following the practices outlined in the above standards will insure a safe environment for both personnel and equipment.

1-6

Chapter 1 General Information

Calibration

The Site Master is a field portable unit operating in the rigors of the test environment. An Open-Short-Load (OSL) calibration should be performed prior to making a measurement in the field. A built-in temperature sensor in the Site Master advises the user, via an icon lo cated on the right side of the LCD screen, that the internal temperature has exceeded a safety window, and the user is advised to perform another OSL calibration in order to main tain 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 optional extension cable; that is, at the same point that you will connect the antenna or device to be tested.

For best results, use a phase stable Test Port Extension Cable (see Optional Accessories). If you use a typical laboratory cable to extend the Site Master test port to the device under test, cable bending subsequent to the OSL calibration will cause uncompensated phase reflections inside the cable. Thus, cables which are NOT phase stable may cause measurement errors that are more pro nounced as the test frequency increases.

For optimum calibration, Anritsu recommends using precision calibration components.

Annual Verification

Anritsu recommends an annual calibration and performance verification of the Site Master and the OSL calibration components by local Anritsu service centers. Anritsu service centers 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 is especially important is the OSL calibration components have been accidentally dropped or over-torqued.

Chapter 2 Getting Started

Introduction

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

Charging a New Battery

The NiMH battery supplied with the Site Master has already completed three charge and discharge cycles at the factory and full battery performance should be realized after your first charge.

NOTE: The battery will not charge if the battery temperature is above 45° Cor below 0° C.

Charging the Battery in the Site Master

The battery can be charged while 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 Master

charging port.

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

for your application.

The green external power indicator on the Site Master will illuminate, indicating the presence of external DC power, the battery charge indicator will light, and the battery will begin fast charging. The charging indicator will remain lit as long as the battery is fast charging. Once the battery is fully charged, the fast charging indicator will turn off and a trickle charge will be started to maintain battery capacity. If the battery fails to charge, contact your nearest Anritsu ser vice center.

NOTE: If a battery is excessively discharged, it may require several hours of trickle charging before the charger will allow a fast charge. Switching to fast charge mode is not automatic. You must either cycle the power on and off, or disconnect and reconnect the AC-DC adapter.

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 optional

charger (Anritsu part number 2000-1029).

2-1

Chapter 2 Getting Started

Batt

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 LED color changes as the battery is charged:

Red indicates the battery is charging Green indicates the battery is fully charged Yellow indicates the battery is in a waiting state (see below).

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 light may 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 the battery fails to charge, contact your nearest Anritsu Service Center.

Determining Remaining Battery Life

When the AC-DC adapter is disengaged, a battery indicator symbol is continuously dis played at the top-left corner of the display (Figure 2-1). A totally black bar within the battery icon indicates a fully charged battery. When LOW BATT replaces the battery indicator bar at the top left corner, a couple of minutes of measurement time remains. If a flashing LOW BATT is accompanied by an audio beep at the end of each trace, the battery has approximately one minute of useable time remaining.

eryIndicator

Figure 2-1. Site Master Battery Indicator

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

The NiMH battery will last longer and perform better if allowed to completely discharge before recharging. For maximum battery life, it is recommended that the NiMH battery be completely discharged and recharged once every three months.

It is normal for NiMH batteries to self-discharge during storage, and to degrade to 80% of original capacity after 12 months of continuous use.

Figure 2-3. NiMH Battery Storage Characteristics

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 2 Getting Started

Important Battery Information

With a new NiMH battery, full performance is achieved after three to five complete

charge and discharge cycles. The NiMH battery supplied with the instrument has already completed three charge and discharge cycles at the factory.

Recharge the battery only in the instrument or in an Anritsu approved charger.

When the instrument or the charger is not in use, disconnect it from the power source.

Do not charge batteries for longer than 24 hours; overcharging may shorten battery life.

If left unused a fully charged battery will discharge itself over time. Storing the battery in

extreme hot or cold places will reduce the capacity and lifetime of the battery. The bat tery will discharge faster at higher ambient temperatures.

Discharge an NiMH battery from time to time to improve battery performance and bat

tery life. The battery can be charged and discharged hundreds of 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. If a battery is allowed to totally discharge, the smart-memory capability of the battery

may be lost, resulting in incorrect battery capacity readings or loss of communication with the battery.

Do not short-circuit the battery terminals.

· Do not drop, mutilate or attempt to disassemble the battery.

Never use a damaged or worn out charger or battery.

Always use the battery for its intended purpose only.

Temperature extremes will affect the ability of the battery to charge: allow the battery to cool down or warm up as necessary before use or charging.

Batteries must be recycled or disposed of properly. Do not place batteries in garbage.

Do not dispose of batteries in a fire.

Functions and Operations

Introduction

This 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 requiring mobility. As such, it is a lightweight, handheld, battery operated unit which can be easily carried to any location, and is capable of up to 2.5 hours of continuous operation from a fully charged battery. Built-in energy conservation features allow battery life to be extended over an eight-hour workday. The Site Master can also be powered by a 12.5 Vdc external source. The external source can be either the Anritsu AC-DC Adapter (P/N 40-115) or 12.5 Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items are standard accesso ries.

Front Panel Overview

The 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 are easily configured for optimum measurements. Selection of one of these keys brings up a function-specific menu on the right hand side of the display. The softkeys adjacent to the display provide access to the various menu items (See Figure 3-1).

Chapter 3 Functions and Operations

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

In situations where there may be a small discontinuity close to a large one, side lobe reduction Windowing should be used. When distance resolution is critical Windowing can be reduced. The types of Windowing in order of increasing side lobe reduction are: rectangular, nominal side lobe, low side lobe, minimum side lobe. Figures 3-7 thru 3-10, on pages 3-11 and 3-12, are examples of the types of Windowing.

Chapter 4 Measurements

Introduction

This chapter provides a description of the Site Master measurement functions and examples of frequency domain, distance domain, and spectrum analysis measurements.

Measurement Functions

Site Master operation is divided into four measurement modes: frequency domain, distance domain, 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 insertion loss of a transmission line over frequency.

Distance domain measurements—commonly known as distance-to-fault (DTF)—are

made over a selectable distance range. They include RL or SWR, but they also return information that can help locate discontinuities in a transmission line. CL cannot be measured in the distance domain.

Spectrum Analysis¾Typical measurements include in-band interference, antenna align-

ment, and cell coverage. Measurements can be easily made by using the main instrument functions: frequency, span, amplitude and sweep. A full range of marker capabilities such as peak, center and delta functions are provided for fast, comprehensive measurement of displayed signals. Limit lines are available for creating quick, simple pass/fail measurements.

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 of power levels above the unit's specified input, the user may attenuate the signal and enter the 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 setup frequency is changed. Calibrations are stored with each of the setups.

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

NOTES: For best calibration results–compensation for all measurement system uncertainties–ensure that the Open/Short/Load is at the end of the test port or optional extension cable; that is, at the same point as the antenna or device to be 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 uncompensated phase reflections inside the cable. Cables that are not phase stable may cause measurement errors that become more pronounced as the test frequency in creases.

Chapter 4 Measurements

Refer to the “Performing a Calibration” procedure on page 4-3 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 the antenna or device to be tested.

For best results, use a phase stable Test Port Extension Cable (see Optional Accessories). If you use a typical laboratory cable to extend the Anritsu test port to 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 more pronounced as the test frequency increases.

For optimum calibration, Anritsu recommends using precision calibration components.

Making a Measurement with the Spectrum Analyzer

Making a measurement with the Anritsu Site Master S114B and S332B is similar to using conventional spectrum analyzers. Users need simply to power-on and tune the Spectrum Analyzer to locate and display a signal on the screen. Once a signal is displayed the user can measure the signal input in four simple steps to determine the frequency and amplitude of the signal. These steps include setting the center frequency, setting the frequency span, setting the amplitude, and activating the marker.

Note: Frequency, span and amplitude are the fundamental functions for spec trum analyzer measurements. However, by using marker functions, you are able to easily read out frequencies and amplitudes on the spectrum analyzer trace. This lets you make relative measurements, automatically locate the sig nal of the highest amplitude on a trace, and tune the spectrum analyzer to track a signal automatically.

Example – Measuring a 900 MHz signal

Step 1. Press ON/OFF then ENTER when prompted. Step 2. Connect a signal generator to the RF input of the Spectrum Analyzer and config

Communication Port Setting

The Site Master Software Tools communicates with the Site Master through a standard COM port on the PC. It is important that your Windows COM port settings conform to the actual hardware settings. Since various add-in devices such as sound cards, modems, and network cards use IRQ (Interrupts), it is possible that your computer has non-standard COM port settings. Please consult your computer vendor for COM port address and IRQ in formation.

Plot Capture

Plots (traces) can be captured either singly from the Site Master display or in multiples from one or more stored-display locations. Both methods are described below.

The recommended method is to capture multiple traces to a database. In one operation, all of the data residing in the up-to-200 stored display memory locations in the Site Master can be downloaded to a database for easy data management.

NOTE: Trace scale can be captured as per Site Master or as autoscale by the capture program. To select per Site Master or autoscaling, click on Settings and Default Plot Settings from the top menu bar and pull-down menu.

Fault Location Software

A captured RL or SWR trace can be transformed to a Distance to Fault display. This is use ful for determining the location of faults, connections, and other discontinuities within the cable.

To transform a plot, select Distance to Fault from the to Fault icon in the toolbar). A drop down menu will appear that asks you if the DUT is co axial cable or waveguide.

If coaxial cable is selected, it asks you to supply start and stop distances along with the ca ble type or propagation velocity and insertion loss values. Tables in Appendix A provide these values for some of the more popular coaxial cables (@ 1000 MHz).

If values are needed at a different frequency, or if you need the exact values for more accurate measurement, please contact the coaxial cable manufacturer. Coaxial cables may be added to the list be editing the cables.lst file. Follow the existing format to enter the data to the list. Loss is entered in dB/m only.

The distance may be entered in feet or meters. Propagation velocity is used for coaxial cable. The units may be changed by selecting and changing Measurement Units.

“Drag-n-Drop”

Site Master Software Tools is Windows based. Graphs can “Drag-n-Drop” onto each other. Site Master Software Tools allows quick comparison of “before” and “after” Distance-ToFault measurements. Recent data is compared to a historical PC database record, which is usually recorded during site installation/commissioning.

Chapter 5 Software Tools Program

Each cable/antenna tends to have a unique Distance-To-Fault (DTF) “Signature” because differing cable electrical lengths, cable types, dielectric thickness variations, and the posi tions of components (connectors, adapters, and lightning arresters) will cause different re flections at differing positions in the transmission line. Variations in the “signature” between maintenance intervals offer a good indication of damage or damage causing condi tions.

Captured traces may be printed from a PC using Site Master Software Tools. Once a cap tured trace has been downloaded choose printer setup can be altered, plots can be scaled, and multiple plots can be printed from the Print dialog box.
