Types of Service Available
If your instrument fails during the warranty period, Keysight Technologies will repair or replace it under
the terms of your warranty. After your warranty expires, Keysight offers repair services at competitive
prices. You may also consider purchasing a service contract that extends coverage after the standard
warranty.
To obtain service for your instrument,
contact your nearest Keysight Technologies Service
Center.
They will arrange to have your unit repaired or replaced, and can provide warranty or repair–cost
information where applicable. Ask the Keysight Technologies Service Center for shipping instructions,
including what components to ship. Keysight recommends that you retain the original shipping carton
for return shipments.
Self-test
The instrument performs an automatic self-test at power-on. This test verifies the basic functionality of
the instrument's logic and power mesh subsystems without placing any voltages on the output.
The *TST? query returns the result of that test, but it does not run another self-test. If self-test fails,
turn the instrument off, remove all connections (front and rear), and turn the instrument back on. The
purpose of this is to eliminate signals present on external wiring that can act as antennae.
