6-9. Oscilloscope Module Removal and Replacement

The effects of ELECTROSTATIC DISCHARGE can damage electronic compo-

nents. Use grounded wrist straps and mats when you are performing any kind of

service on this module.

When you need to remove and replace a module, test the module first to determine the faulty part. If

either of the trigger cables are faulty, remove the faulty cable and replace it with a new one. Refer to para-

graph 6-10 for procedures to remove and replace a faulty cable. If either of the attenuators are faulty, re-

move the faulty attenuator and replace it with a new one. Refer to paragraph 6-11 for procedures to re-

move and replace a faulty attenuator.

Oscilloscope Module Removal Procedure:

ment power is turned off.
