Introduction to
This Section
This section covers performance checks used to verify that the radio meets
published specifications. The recommended test equipment listed in the previous
section approaches the accuracy of the manufacturing equipment, with a few
exceptions. Accuracy of the equipment must be maintained in compliance with the
manufacturer’s recommended calibration schedule. Checks should be performed
if radio performance degradation is suspected.
Setup Supply voltage can be connected from the battery eliminator. The equipment
required for alignment procedures is connected as shown in the “Radio Alignment
Test Setup” diagram (Figure 4).
