Chapter 1 General Information

Introduction

This chapter provides description, specification, and optional accessories for the Site Master Series instruments. This series has two members, as shown below. Throughout this manual, the term Site Master will refer to the series; whereas, the terms Site Master S112, S113 will refer to the applicable individual models.

S112 5 to 1000 MHz S113 5 to 1200 MHz

Frequency Range

Description

The Site Master (Figure 1-1) is a hand held SWR/RL(standing wave ratio/return loss) and Distance-To-Fault measurement instrument that includes a built-in synthesized signal source and an optional power monitor. It uses a keypad to enter data and a liquid crystal display (LCD) to provide a graphical indication of SWR or RL over the selected frequency range. The Site Master S113 has a built-in distanceto-fault capability. The Site Master S112, as well as model S113, allows measurement data to be converted to Fault Location via the companion Software Tools program. The Site Master is capable of up to two hours of continuous operation from a fully charged internal battery. It can also be operated from a 12.5 dc source (which will also simulta-

Chapter 1 General Information

neously charge the battery). 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 capability is available as an option. The displayed trace can be scaled and/or enhanced with settable frequency markers and/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

A PC based software program (called Software Tools) provides an online database record for storing measurement data. Site Master Software Tools can also convert the Site Master display to a Microsoft Windows 3.x graphic. Measurements stored in the Site Master internal memory are down-loaded to the PC using the included serial cable. This null-modem serial cable connects between the Serial Interface connector on the Site Master and a Com Port on a DOS/Windowsbased PC. Once stored, the graphic trace can then be displayed, scaled, and/or enhanced with markers and limit lines. Historical graphs can be overlaid with current data by using the PC’s mouse in “drag-n-drop” fashion. The underlying data can be extracted and used in spreadsheets or for other analytical tasks.

The Software Tools program also performs DTF (Distance To Fault) or Fault Location by clicking on the appropriate icon.

to make a selection. This feature is provided as a rapid means of setting both cable loss and propagation velocity.

WINDW — Opens a menu of FFT windowing

types for the DTF calculation. Use the Up/Down Arrow key and ENTER key to make a selection.

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 2-4 thru 2-7, on pages 2-14 and 2-15, are examples of the types of Windowing.

Remote Operation

All Site Master functions, settings, and operating modes (except for power on/off) are controllable using commands sent from an external computer via the serial port. A detailed description of the programming commands is available in the Site Master Programming Manual, P/N 10580-00012.

Operating Procedures

Site Master operation can be divided into four functional areas: common functions, frequency domain, distance domain, and power monitor.

• Common functions are options and scale functions that are

common to both frequency- and distance-domain measurements.

•

Frequency domain measurements consist of Return Loss (RL), Standing Wave Ratio (SWR), and Cable Loss (CL) made over a selectable frequency range. RL and SWR characterize the magnitude of reflections present in a device or transmission line. CL measurements 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 informa-

2-20

Chapter 2 Operation

tion that can help locate discontinuities in a transmission line. CL cannot be measured in the distance domain.

Power monitor measurements can be either absolute or rela-

•

tive 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 display. Finally, a zero adjust function is provided to allow substraction of an inherent “noise” level prior to display.

CAUTION: The measurement system MUST be calibrated at the ambient temperature prior to making a measurement. You must calibrate when the setup frequency is changed. The instrument can store up to two calibrations. These stored calibrations are independent of any stored setups. When you recall a stored setup, perform a new calibration or recall a stored calibration.

If, during a calibration, you wish to repeat a measurement or change the order in which the Open, Short, and Load are connected, press Up/Down Arrow key.

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 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 port to the device-under-test, cable bending subsequent to the Open/ Short/Load calibration will cause uncompensated phase reflections inside the cable. Thus, cables which are NOT phase stable may cause measurement errors that are more pronounced as the test frequency increases.

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 the Capture Multiple Traces option in the Capture pull-down menu. Using this method, you can download to the Software Tools program in one operation all of the data residing in the up-to-40 Stored Display memory locations. The downloaded traces will appear in cascade on the PC screen.

Multiple trace capture (preferred method)

Step 1. Connect the supplied cable as shown in Figure 3-3. Step 2.

Step 3.

Open the “Site Master Software Tools” group, in the Windows Program Manager. (Select the Windows pull-down menu from the Pro-

gram Manager menu bar, and select Site Master Software Tools.)

Fault Location Software

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

To transform a plot, select Fault Find from the Tools menu (or click the toolbar button). A drop down menu will appear that asks you to supply start and stop distances, along with dielectric constant or propagatiion velocity and insertion loss values. The table on the inside of the manual back cover provides these values for some of the more popular cables. The values are given at a nominal frequency of 1000 MHz. If values are needed at a different frequency, or if you need the exact values for more accurate measurement, please contact the cable manufac-

turer. Cables may be added to the list be editing the file and following the existing format. The distance may be entered in feet or meters. Propagation velocity or dielectric constant may be used. The units may be changed by selecting Default Plot Settings under the Settings menu and changing “Distance Units” or “Cable Units.”

After supplying the needed information and clicking OK, a new plot will open showing cable match vs. distance.

“Drag-n-Drop”

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

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 positions of components

(connectors, adapters, and lightning arrestors) will cause different reflections at differing positions in the transmission line. Variations in the “signature” between maintenance intervals offer a good indication of damage or damage causing conditions.

Printing

Captured traces may be printed from a PC using Site Master Software Tools. Once a captured trace has been downloaded choose Print under the File menu for printing options. The printer setup can be altered, plots can be scaled, and multiple plots can be printed from the Print dialog box.
