Specifications

Keysight Technologies Calibration Services
When your instrument is due for calibration, contact your local
Keysight Service Center for a low-cost recalibration. The 34970A is
supported on automated calibration systems which allow Keysight to
provide this service at competitive prices.
Calibration Interval
The instrument should be calibrated on a
regular interval determined
by the measurement accuracy requirements of your application.
A 1-year interval is adequate for most applications. Accuracy
specifications are warranted only if adjustment is made at regular
calibration intervals. Accuracy specifications are not warranted
beyond the 1-year calibration interval. Keysight does not recommend
extending calibration intervals beyond 2 years for any application.
Adjustment is Recommended
Whatever calibration interval you select, Keysight recommends that
complete re-adjustment should always be
performed at the calibration
interval. This will assure that the 34970A 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.
Use the Calibration Count feature (see page 69) to verify that all
adjustments have been performed.
