Obtaining Service
Operating Checklist
Before returning your instrument to Keysight for service or repair check the
following items:
Is the instrument inoperative?
– Verify that the power cord is connected to the instrument and to ac line power.
– Verify the front panel power switch is depressed.
Does the instrument fail self–test?
– Remove all test connections to the instrument and run the self–test again.
Errors may be induced by ac signals present on the instrument input terminals
during self–test. Long test leads can act as an antenna causing pick–up of ac
signals.
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.
Extended Service Contracts
Many Keysight products are available with optional service contracts that extend
the covered period after the standard warranty expires. If you have such a service
contract and your instrument fails during the covered period, Keysight
Technologies will repair or replace it in accordance with the contract.
