Calibrating for Increased Measurement Accuracy
Calibration Kits
Step 3: 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 with the
user-defined 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. NIST-traceable
standards (such as HP verification standards) are recommended to
achieve verifiable measurement accuracy.
CAUTION
The published specifications for your analyzer system include accuracy
enhancement with compatible calibration kits. Measurement
calibrations made with user-defined calibration kits are not subject to
those analyzer specifications.
To preset one of the ten User Cal Kits (User Cal Kit A–J) to a type-N(f)
calibration kit, press
. Use the up or down
arrows or the front panel knob to highlight the User Cal Kit you wish to
preset. Press
.
To preset all of the ten User Cal Kits (User Cal Kit A–J) to type-N(f)
calibration kits, press
. Use the up or down
arrows or the front panel knob to highlight one of the User Cal Kits.
Press
.
When this preset is done, the size of your saved instrument state
becomes slightly smaller since the instrument doesn’t save the
user-defined calibration kit. The instrument state can be saved by
pressing
. Refer to
Measurement Results” on page 4-55
