Performance Checks
5
Introduction This section covers performance checks used to ensure 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 test 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 Figure 4.
Figure 4. Radio Alignment Test Setup
Initial equipment control settings should be as indicated in Table 5 on
page 14, and should hold for all alignment procedures, except as noted.
