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"
(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 PNA as an independent instrument. The
equipment and measurement standards used for the tests must be certified and must be traceable to
recognized standards.
NOTE 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.
