Keysight Technologies Calibration Services
When your meter is due for calibration, contact your local Keysight Technologies
Service Center for a low-cost recalibration. The Keysight 34420A is supported on
automated calibration systems which allow Keysight Technologies to provide this
service at competitive prices. Calibrations to MIL-STD-45662 are also available at
competitive prices.
Calibration Interval
The meter should be calibrated on a regular interval determined by the
measurement accuracy requirements of your application. A 1-year or 2-year
interval is adequate for most applications. Keysight Technologies does not
recommend extending calibration intervals beyond 2 years for any application.
Whatever calibration interval you select, Keysight Technologies recommends that
complete re-adjustment should always be performed at the calibration interval.
This will increase your confidence that the Keysight 34420A will remain within
specification for the next calibration interval. This criteria for re-adjustment
provides the best long-term stability. Performance data measured using this
method can be used to extend future calibration intervals.
Time Required for Calibration
The Keysight 34420A can be automatically calibrated under computer control.
With computer control you can perform the complete calibration procedure and
performance verification tests in less than 50 minutes. Manual calibrations using
the recommended test equipment will take approximately 2 hours.
Automating Calibration Procedures
You can automate the complete verification and adjustment procedures outlined
in this chapter if you have access to programmable test equipment. 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 can also enter calibration constants from the remote interface. Remote
operation is similar to the local front-panel procedure. You can use a computer to
