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 proce-
dures, 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.

General Information
Introduction
This chapter provides description, specification, and optional accesso-
ries for the Site Master Series instruments. This series has two mem-
bers, 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.
Model Frequency Range
S112 5 to 1000 MHz
S113 5 to 1200 MHz
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 se-
lected frequency range. The Site Master S113 has a built-in distance-
to-fault capability. The Site Master S112, as well as model S113, al-
lows measurement data to be converted to Fault Location via the com-
panion 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-
1-1
1

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 on-
line database record for storing measurement data. Site Master Soft-
ware 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/Windows-
based 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 fre-
quency is used.

Operation
Introduction
This chapter provides a description of each control and describes how
to calibrate the Site Master and make a measurement.
Control Descriptions
Control descriptions are given below; the test panel controls and con-
nectors are listed first. The keypad controls follow and are listed alpha-
betically. Then, the soft keys and menu structure are described using
Figure 2-3 (page 2-7).
Test Panel
12.5-15VDC
(600 mA) Provides input for battery charging the unit. Input is 12.5 to 15 Vdc @ 600 mA.
Battery
Charging Indicator light to show that the battery is being charged.
External
Power Indicator light to show that the Site Master is being
powered by the external charging unit.
Serial
Interface Provides an RS232 DB9 interface with a Com Port on a personal computer (for use with the ANRITSU
Software Tools program). Also provides an interface
2-1
2

to a HP Deskjet 340 printer or a Seiko DPU-411
Thermal printer.
Test
Port Provides RF output, 50Wimpedance.
RF Det Provides RF detector input for the Power Monitor.
Keypad
Turns the liquid crystal display (LCD) back-lighting
ON or OFF. (Leaving back lighting off conserves
battery power.)
AUTO
SCALE Automatically scales the display for optimum resolu- tion.
CAL Opens a calibration menu. Use Up/Down Arrow key
and ENTER key to select a stored calibration (A or
B) or turn CAL off.
ENTER Implements certain menu and key selections.
ESCAPE
CLEAR Exits the present operation and/or clears the display. If a parameter is being edited, pressing this key will
clear the value currently being entered and restore the
last valid entry. Pressing this key again will close the
parameter. During normal sweeping, pressing this
key will move up one menu level.
LIMIT Calls up the Scale Menu.
MARKER Calls up the Marker Menu.
ON
OFF Turns the Site Master on or off. When turned on, the
system state at the last turn-off is restored. If the
2-2
Chapter 2 Operation

ESCAPE key is held down, the factory preset state is
restored.
PRINT Prints the current display to the selected printer.
RECALL
DISPLAY Recalls a previously saved trace from memory loca- tion 1 through 40. When the key is pressed, “Recall
display:” appears on the display. Select an appropri-
ate number from the keypad and press the ENTER
key to implement.
RECALL
SETUP Recalls a previously saved setup from memory loca- tion 0 through 9. When the key is pressed, “Recall
Setup:” appears on the display. Select an appropriate
number from the keypad and press the ENTER key
to implement. Setup 0 recalls the factory preset state.
RUN
HOLD When in the Hold mode, this key starts the Site Mas-
ter sweeping and provides a Single Sweep Mode
trigger; when in the Run mode, it pauses the sweep.
When in the Hold mode, the hold symbol (Table 2-1,
page 2-45) appears on the left side of the LCD.
(HOLD conserves considerable battery power.)
SAVE
DISPLAY Saves the displayed trace to 1 of 40 internal non- volatile memory locations. When the key is pressed,
“Save display:” appears on the display. Select an ap-
propriate number from the keypad and press the
ENTER key to implement.
CAUTION:The selected memory location will be over-
written by the SAVE DISPLAY operation. No warning
is given.
2-3
Chapter 2 Operation

SAVE
SETUP Saves the current system setup to 1 of 9 internal non-volatile memory locations. When the key is
pressed, “Save Setup:” appears on the display. Select
an appropriate number from the keypad and press the
ENTER key to implement.
CAUTION:The selected memory location will be over-
written by the SAVE SETUP operation. No warning is
given.
START
CAL Opens a calibration menu. Use the Up/Down Arrow
key and ENTER key to select the location to store
the calibration (A or B) or cancel the command. The
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:
qConnect OPEN, Press ENTER
The Site Master then measures the “open” test
port (standard calibration), or the calibration
“open” (precision calibration kit) that you must at-
tach to the end of the test port or transmission line.
qConnect 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.
