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.
v
Please Recycle
This product contains a rechargeable nickel-
cadmium battery. Spent nickel-cadium bat-
teries are valuable resources, do not throw
them away. Arrange for proper return for re-
cycling in your locality. If you do not have
access to proper disposal methods, return the
battery to your ANRITSU service center.
Service centers will dispose of the unit at no
charge. ANRITSU service centers are listed
in Table 2-4 (page 2-58).

Chapter 1
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 S810A and
S818A will refer to the applicable individual models.
Model Frequency Range
S810A 3.3 to 10.5 GHz
S818A 3.3 to 18.0 GHz
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 has a built-in distance-to-
fault capability. The Site Master is capable of up to two hours of con-
tinuous operation from a fully charged internal battery. It can also be
operated from a 12.5 dc source (which will also simultaneously 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 coax/
waveguide 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
1-1

“beep” when the limit value is exceeded. To permit use in low-light en-
vironments, 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 95 or 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 dis-
played, 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 and Smith Chart by clicking on the appropriate icon.
The following items are supplied with the basic hardware.
•Soft Carrying Case
•AC-DC Adapter
•Automotive Cigarette Lighter 12 Volt DC Adapter
•3 1/2-inch floppy disk containing the Software Tools program.

** 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 or
group velocity of the waveguide 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 2-8).
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. (Indicator automatically shuts off when the
battery is fully 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
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 Displays the calibration configuration—the type of
calibration, the frequency range, the valid tempera-
ture range of the calibration, and the current tempera-
ture.
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, described on page 2-12.
MARKER Calls up the Markers Menu, described on page 2-21.
ON
OFF Turns the Site Master on or off. When turned on, the
system state at the last turn-off is restored If the ES-
CAPE/CLEAR 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 70. 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 6. When the key is pressed, “Recall
Setup:” appears on the display. Select an appropriate
2-2
Chapter 2 Operation

number using the Up/Down Arrow key and press the
ENTER key to implement. Setup 0 recalls the fac-
tory 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 2-54) appears on the left side of the LCD.
(HOLD conserves considerable battery power.)
SAVE
DISPLAY Saves the displayed trace to 1 of 70 internal non-volatile memory locations. When the key is
pressed, the next available empty memory location
appears on the display (i.e.“Save display 3”). Press
ENTER to save to the current empty memory loca-
tion or select an appropriate number from the key-
board or use the Up/Down Arrow key and press the
ENTER key to implement.
To erase saved displays select 0 and press ENTER.
Individual displays may be selected and erased by en-
tering the display number and pressing ENTER. Se-
lecting display 0 will erase all saved displays.
CAUTION:The selected memory location will be over-
written by the SAVE DISPLAY operation. No warning
is given.
When the Site Master is cycled on/off, the memory
location increment resets to the lowest memory loca-
tion (1).
SAVE
SETUP Saves the current system setup to 1 of 6 internal non-volatile memory locations. When the key is
pressed, “Save Setup:” appears on the display. Select
an appropriate number using the Up/Down Arrow
key and press the ENTER key to implement.
