4 Calibration, Verification, and Service
Calibration Overview
This section contains information regarding the instrument's calibration.Be sure to read through the
overview first, and follow the steps in order.
Closed–Case Electronic Calibration
The instrument uses closed-case electronic calibration; no internal adjustments are required. The
instrument calculates correction factors based on reference signals that you apply and then the user
stores the correction factors in nonvolatile memory. This data is not changed by cycling power or *RST.
Keysight Technologies Calibration Services
Keysight Technologies offers calibration services using automated calibration systems that enable
Keysight to provide calibration at competitive prices. See

Calibration Interval
The instrument should be calibrated on a regular interval determined by the 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.
Time Required for Calibration
The instrument can be automatically calibrated under computer control, including complete
calibration procedure and performance verification tests, in approximately 30 minutes once the
instrument is warmed–up.
