System-Related Operation

This section provides information on system-related topics such as executing a
self-test, performing a self-calibration routine, and reading error conditions.

Self-test

To perform the self-test, proceed as follows.
Keysight Measurement Manager operation
Disconnect all connections from the output terminals.
Ensure that the output terminals are not connected to any loads. Turn on the
U2722A/U2723A. On the application panel, select Tools > Sel f-Test.
If the self-test fails, an error is recorded in the instrument error queue.
Use the SYSTem:ERRor? query from the remote interface (see the Keysight
U2722A/U2723A USB Modular Source Measure Units Programmer's Reference).
A list of the possible self- test errors is given on
– If repair is required, contact a Keysight Service Center.
– If all tests pass, you have a high confidence (~90%) that the instrument is

Self-calibration

To perform a self-calibration, proceed as follows.
Keysight Measurement Manager operation
Disconnect all connections from the output terminals.
Unplug any cables connected to the U2722A/U2723A before performing the
self-calibration to prevent the occurrence of process failure. On the application
panel, select Tools > Sel f-Calibration.
The source must be powered-up for at least 45 minutes before performing the
NOTE
self-test and the self-calibration.
