Certificate of Calibration

Keysight Technologies will issue a certificate of calibration upon successful
completion of system verification or completion of the performance tests. The
certificate of calibration will apply to the "system" (network analyzer,
calibration kit, test cables, and any necessary adapters) if the system
verification procedure is used to confirm the system specifications. If the
performance tests are used to confirm instrument specifications, the certificate
of calibration will apply to the network analyzer 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 network 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.
