Verify Performance - Agilent Technologies 8719D User Manual

Verify performance

Once a measurement calibration has been generated with a user-del?ned calibration kit, its
performance should be checked before making device measurements. lb check the accuracy
that can be obtained using the new calibration kit, a device with a well-defined frequency
response (preferably unlike any of the standards used) should be measured. The verification
device must not be one of the calibration standards: measurement of one of these standards is
merely a measure of repeatability.
To achieve more complete verification of a particular measurement calibration, accurately
known veri&ation standards with a diverse magnitude and phase response should be
used. National standard traceable or HP standards are recommended to achieve verifiable
measurement accuracy.
The published specifications for the HP 8719D/20D/22D network analyzer
Note
system include accuracy enhancement with compatible calibration kits
Measurement calibrations made with user-defined or modilled calibration kits
are not subject to the HP 8719D/20D/22D specifications, although a procedure
similar to the system verification procedure may be used.
