How to Use this Manual

The operation of the Site Master ™ is straightforward and intuitive.
However, you may find it helpful to review the operation of the keys
and menus prior to first-time use.

Descriptions of the keys and menus, along with measurement proce­dures, are provided in Chapter 2.

First-time users and maintenance supervisors will benefit from perusing
the material in Chapter 1. This chapter describes the instrument and
provides listings of options and performance specifications.

Please Recycle

This product contains a rechargeable bat­tery. This battery may be recyclable. For en­vironmental reasons, you should dispose of
the battery in a proper manner at the end of
equipment life. If you do not have access to
proper disposal methods, return the battery
to your ANRITSU service center.
ANRITSU will dispose of the unit at no
charge. ANRITSU service centers are listed
in Table 2-4 (page 2-50).

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

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.

** Fault location is accomplished by inverse Fourier Transformation of data taken with
the Site Master. Resolution and maximum range depend on the number of frequency
data points, frequency sweep range and relative propagation velocity of the cable being
tested.

*** Immunity measurement is made in CW mode with incoming intefering signal exactly
at the same frequency (worst case situation). Typical immunity is better when swept fre­quency is used.

existing calibration in the location chosen will be
overwritten once the calibration is performed.

Follow the text in the message area that instructs you
to do the following:

q

Connect OPEN, Press ENTER

The Site Master then measures the “open” test
port (standard calibration), or the calibration
“open” (precision calibration kit) that you must at­tach to the end of the test port or transmission line.

2-4

q

Connect SHORT, Press ENTER

The Site Master then measures the calibration
“short” that you must attach to the end of the test
port or transmission line.

Chapter 2 Operation

Connect LOAD, Press ENTER

q

The Site Master then measures the 50W termina­tion (load) that you must attach to the end of the
test port or transmission line.

NOTES:
The order of the “Open,” “Short,” and “Load” meas­urements can be changed or the selection repeated
using the Up/Down Arrow Key.

The combined measurements of an open, a short,
and a known-impedance load normalizes the meas­urement system, to account for uncertainties intro­duced by measurement-system components (e.g.,
cables, connectors, etc.).
