Calibration Procedures 3
Keysight 34980A Service Guide 33
Performance data measured during Performance Verification Tests does not
guarantee the instrument will remain within these limits unless the adjustments
are performed.
Use the Calibration Count feature (see page 36) to verify that all adjustments have
been performed.
Time Required for Calibration
The 34980A can be automatically calibrated under computer control.
With computer control you can perform the complete calibration procedure and
performance verification tests in less than 30 minutes once the instrument is
warmed-up (see “DMM Test Considerations” on page 42).
Automating Calibration Procedures
You can automate the complete verification and adjustment procedures outlined
in this manual. You can program the instrument configurations specified for each
test over the remote interface. You can then enter readback verification data into
a test program and compare the results to the appropriate test limit values.
You must adjust the instrument using the remote interface. Adjustment cannot be
performed from the local front-panel. The instrument must be unsecured prior to
initiating the calibration procedure (see “Calibration Security” on page 35).
For further information on programming the instrument, see Chapter 2 in the
34980A User's Guide.
For information about errors that may occur during the calibration procedure, see
“Calibration Errors” on page 76.
