To test the CRT monitor signals

To test the CRT monitor signals

Refer to chapter 6, "Replacing Assemblies," for instructions to remove or replace covers and assemblies.

Hazard voltages exist on the power supply, the CRT, and the CRT driver board. This procedure is to be performed by service-trained personnel aware of the hazards involved, such as fire and electrical shock.

1Remove the cover of the instrument.

2Check the CRT monitor input cable for the signals and the power supplies listed in the table below. The cable is the wide ribbon cable connecting the monitor to the acquisition board.
