When Using the
Optional HP 8517B
Test Set
To help locate the faulty instrument, the service adapter (HP part number
85102-60210) is used to emulate the operation of the source and test set and
check unratioed power levels into the HP 85102 IF/Detector.
NOTE
When checking any unratioed power levels, turn the HP 8510 averaging
OFF. Refer to “Unratioed Power Test” in the HP 8517B Operating and

power level of each test set sampler/mixer assembly and its associated IF
amplifier. Depending upon the test outcome, the procedure directs you to the
most likely cause of failure.
