Keysight Technologies calibration services

When your instrument is due for calibration, contact your local Keysight Service
Center for a low-cost recalibration. The U2722A/U2723A is supported on
automated calibration systems, which allows Keysight to provide this service at a
competitive price.

Calibration interval

A one-year interval is adequate for most applications. Accuracy specifications are
under warranty only if adjustments are made at regular calibration intervals.
Accuracy specifications will not be offered warranty beyond the one-year
calibration interval. Keysight does not recommend extending calibration intervals
beyond two years for any application. Keysight recommends that a complete
readjustment should always be performed at the calibration interval. This will
ensure that the U2722A/U2723A will remain within specifications for the next
calibration interval. The readjustment provides the best long-term stability and
accuracy.

Types of service available

If your instrument fails during the warranty period, Keysight will repair or replace it
under the terms of your warranty. After your warranty expires, Keysight offers
repair services at competitive prices.

Extended service contracts

Most Keysight products are provided with optional service contracts that extend
the coverage period after the standard warranty expires. If you have this service
contract and your instrument happens to fail during the coverage period, Keysight
will repair or replace it according to the contract.
