Analog Duplex System
Introduction
The 3900 Analog Duplex System tests mobile radio transmitters, receivers and transceivers. The tests
can be simple functionality tests or more detailed tests such as testing transmitter power output, broad
band and narrow band; receiver sensitivity; AM and FM modulation and demodulation performance;
distortion level and SINAD.
The Analog Duplex System includes the following test functions:
● AM and FM Signal Generator
● RF Signal Analyzer
● Multiple AF Signal Generators
● Multiple AF Modulators
● AF Measurement
● Modulation Measurement
● Oscilloscope
for examining external and internal signals
● Full Duplex operation
● Spectrum Analyzer, Channel Analyzer and Audio Analyzer.
This chapter explains how to use the Analog Duplex System. Refer to Chapter 3, Test Set Operation
, for
general operation of the Test Set. This chapter includes the following:
● Description of the Analog Duplex System and a diagram of a common test setup.
● Describes how to access the Analog Duplex System.
● Describes how to navigate Analog Duplex System Tiles.
● Describes the layout and information provided on Analog Duplex Tiles.
● Explains the TEST Tiles.
