14 U2722A/U2723A Service Guide
2Getting Started
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.
