Operation Verification
Operation verification is a series of tests that, when completed, will either ensure that the signal generator is
operating correctly, or will assist in pointing to the problem area. Operation verification does not ensure
performance to specifications, but should provide a level of confidence that the signal generator is operating
correctly within a minimum amount of time.
Operation verification is appropriate for incoming inspection, after repair (when a full calibrated
performance is not required), or whenever the integrity of the signal generator is in question.
Perform the following tests in the order they are presented. The tables referenced by the tests are located in
the rear of the chapter, where they can be copied easily.
