Testing AMPS Base Stations
Connecting the Test Set to Your Base Station
Connecting the Test Set to Your Base Station
The connections shown in Figure 2-1 indicate a “generic” base station
using a test interface for audio test signals and a laptop computer
running a control program to control the base station. A power splitter
is used for testing the receiver ports. Although this is a common setup
for performing tests, audio and RF connections to base stations and the
ways base stations are controlled vary among manufacturers.
