1-30 N67xx DUT Power Supply Installation
Verifying Operation
1 Look at the Testhead Config screen and verify that the official configuration
agrees with the actual configuration.
2 Run Diagnostics, especially the DUT power supply tests, with a pin verification
fixture.
In Case of Difficulty
If you need phone support, go to www.keysight.com/find/contactus for contact
information.
If Diagnostics fails, verify that there are no shorting straps on
the terminals. Some supplies come from the factory with
shorting straps. They must be removed to do remote sensing.
