Performance Tests Procedures
Performance Tests Procedures
Test equipment and accessories required to perform maintenance are listed in
Table 4. Equipment other than recommended models can be used provided the
minimum specifications are satisfied.
The performance tests assume the use of a standard amplifier with BNC connec-
tors. If an amplifier with Type-N connectors is to be tested, suitable adapters will
have to be added to the equipment lists.
The performance tests and adjustment procedure cover all three amplifiers. Where
required, test steps list equipment settings, and other additional information, for
each amplifier. If a test step lists only one setting or specification, it is valid for all
three amplifiers. Disregard references to any amplifier not being tested.
