Performance
Calibrating for Increased Measurement
Accuracy
Choose an Appropriate Calibration Method
Once a measurement calibration has been generated with a user-defined
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
verikation
device must not be one of the calibration standards: measurement of one of
these standards is merely a measure of repeatability.
‘lb achieve more complete verifkation of a particular measurement
calibration, accurately known verification standards with a diverse magnitude
and phase response should be used. NBS traceable or HP standards are
recommended to achieve
verihable
measurement accuracy.
CAUTION
The published
specikations
for your analyzer system include accuracy
enhancement with compatible calibration kits. Measurement calibrations
made with user-dehned or modified calibration kits are not subject to those
analyzer
speciEcations.
