9.2 Performance Verification Procedures
This section contains procedures and information for verifying that the 2500B is operating within its specifications. The
specifications for the 2500B start on page 86. Compare the results of the performance verification tests to the
appropriate sections in the Specifications chapter to verify that the 2500B is operating within specifications.
Note the following about performance verification:
Performance verification is recommended at least every two years, or more often when required to ensure proper
operation of the instrument.
Each piece of test equipment must be warmed up according to its specifications prior to testing.
The minimum warm-up time before testing the 2500B is 30 minutes unless otherwise specified.
The following procedures refer to the instrument under test as the 2500B for all 2500B Series Microwave Signal
Generator models.
