Label Class Menu
The label class menus are used to define meaningful labels for the calibration classes.
These then become softkey labels during a measurement calibration. Labels can be up to
ten characters long.
Label Kit Menu
This softkey within the modify cal kit menu, accesses this menu. It is
LABEL KIT
identical to the label class menu and the label standard menu previously described. It
allows definition of a label up to eight characters long.
After a new calibration kit has been defined, be sure to specify a label for it. Choose a label
that describes the connector type of the calibration devices. This label will then appear in
the softkey label in the correction menu and the
CAL KIT [ ]
select cal kit menu. It will be saved with calibration sets.

Verify performance

Once a measurement calibration has been generated with a user-defined calibration kit,
its performance should be checked before making device measurements. To 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 verification standards with a diverse magnitude and phase response should be
used. National standard traceable or Agilent standards are recommended to achieve
verifiable measurement accuracy.
The published specifications for this network analyzer system include
NOTE
accuracy enhancement with compatible calibration kits. Measurement
calibrations made with user-defined or modified calibration kits are not
subject to the analyzer specifications, although a procedure similar to the
system verification procedure may be used.
