Quick Performance Check
The quick performance check is a combination of internal self-test and an
abbreviated performance test (specified by the letter Q in the performance
verification tests). This test provides a simple method to achieve high
confidence in the function generator’s ability to functionally operate and
meet specifications. These tests represent the absolute minimum set of
performance checks recommended following any service activity.
Auditing the function generator’s performance for the quick check points
(designated by a Q) verifies performance for “normal” accuracy drift
mechanisms. This test does not check for abnormal component failures.
To perform the quick performance check, do the following:
Set the function generator to the default power on state (power on default).
A procedure is given on page 41.
Perform a complete self-test. A procedure is given on page 21.
Perform only the performance verification tests indicated with
the letter Q.
If the function generator fails the quick performance check, adjustment or
repair is required.
Performance Verification Tests
The performance verification tests are recommended as acceptance tests
when you first receive the function generator. The acceptance test results
should be compared against the 1 year test limits. After acceptance, you
should repeat the performance verification tests at every calibration interval.
If the function generator fails performance verification, adjustment or
repair is required.
