1. INTRODUCTION

This manual provides maintenance instructions for
the Site Master S820A Antenna and Coax/ Wave

­guide Analyzer. It describes the product and provides
performance verification procedures, parts replace

-

ment procedures, and a replaceable parts list.

2. DESCRIPTION

The Site Master (Figure 1) is a hand held SWR/RL
(standing wave ratio/return loss) and Distance-To­Fault measurement instrument. It combines a syn

­thesized source, VSWR Bridge, and receiver on a
single printed circuit board (PCB). An optional
power monitor is also available. A block diagram is
shown in Figure 2.

3. PERFORMANCE VERIFICATION

Paragraphs 4 through 7 contain tests that can be
used to verify the performance of the Site Master
model S820A having any version of firmware.

3.1. Initial Setup for Testing

1. Press and hold the
then press the

ESCAPE/CLEAR key,

ON/OFF key to turn on the

Site Master. (This sets the instrument to
the factory preset state.)

2. Release the

ESCAPE/CLEAR key and use

the Up/Down Arrow key to adjust the
contrast to give a readable display.

5. RETURN LOSS VERIFICATION

The following test can be used to verify the accuracy
of return loss measurements. Verification is per
formed by measuring the Source Match and Cor

-

­rected Directivity. This method eliminates the uncer
tainties of measuring standard offset. Measurement
calibration of the Site Master is required for this
test.

Refer to the RF Measurement Chart on page 12, and
the Return Loss Verification worksheet on page 13.

8. Use the RF Measurement Chart to corre

­late the peak-to-peak ripple reading to a
return loss value in dB. The measured
value should be:
£ –18 dB (3.3 - 10.5 GHz)

-

£ –14 dB (10.5 - 20 GHz).

mination. Verify that noise spikes are be
low 44 dB and that the trace is smooth.
Repeat as required.

12. Measure and record the worst case
peak-to-peak ripple.

13. Add this value to the mean value of the
29KF50-15 Precision Offset Termination.

14. Use the RF Measurement Chart to corre

­late the reading to a return loss value in
dB. The measured value should be:
£ –29 dB (3.3 - 20 GHz).

The battery used in the Site Master is a recharge
able nickel-cadmium (NiCd) battery and is covered

­by the Battery Directive (91/157/EEC). As such, the
battery is marked as follows to indicate controlled
disposal.

This marking indicates that
the battery is a recyclable
product.

This marking indicates that
the battery requires separate
collection and shows the
chemical system (Nickel/
Cadmium).

Component

Nickel 19 to 26%
Cadmium 17 to 22%

% of Cell

Weight

This marking indicates the
heavy-metal component
concentration as a percentage
of battery cell weight.

Spent nickel-cadmium batteries are valuable re­sources. Because they are reusable, do not throw
them away. Arrange for proper return for recycling
in your locality. If you do not have access to proper
disposal methods, return the battery pack to your
Anritsu service center. Service centers will dispose of
the unit at no charge. Anritsu Service Centers are
listed on page 14 of this manual.
