Performance Verification Tests Overview

To perform a calibration run, the performance verification tests listed in the table below must be completed.  If any of the performance verification tests fail, perform the corresponding calibration adjustment.

If the performance verification tests fail and no calibration adjustment procedure is available, the instrument must be returned to Keysight Technologies for repair. See Contacting Keysight Technologies..
