About System Verification and Performance Tests
PNA as an independent instrument. The equipment and measurement
standards used for the tests must be certified and must be traceable to
recognized standards.
If you have a measurement application that does not use all of the
measurement capabilities of the analyzer, you may ask your local Keysight
Technologies service office to verify only a subset of the specifications.
However, this “limited calibration” creates the possibility of making
inaccurate measurements if you then use the analyzer in an application
requiring additional capabilities.
