A qualified Engineer or Technician should be responsible for designing and evaluating the alternative Heat Sinking method. Certificates of compliance are available. RF performance data is recorded and inspected for conformance within the limits set forth in Table 1. Currently, each unit is subjected to a DC burn-in test for 72 hours with the input and output ports terminated in 50 ohms. This is a worst case condition for the amplifier since, when terminated, the DC power dissipated in the amplifier circuitry exceeds the amount dissipated when Class A RF power is being generated.
Performance is compared before and after the DC burn-in.
Acceptance Test Procedure Test Setup Figure 4 illustrates the test position setup used to perform acceptance testing on the LZY-2 for the majority of the performance parameters specified in Table 1. The test equipment required to perform the acceptance tests is detailed in Table 2. In the event any item of test equipment is unavailable, substitution of equivalent equipment is suggested. All test equipment should be turned on 30 minutes prior to start of test. All LZY-2 amplifiers are warranted to be free from defects in material and workmanship for a period of one year from date of shipment.
