Anritsu 373XXA Chapter 5 Troubleshooting

Chapter 5Troubleshooting

5-1 INTRODUCTION This chapter provides specific procedures to be followed when trouble-

shooting 373XXAVNA systems. While performing these procedures, al-

ways observe the warnings and cautions on the opposite page.

Touse the troubleshooting procedures in this chapter:

1. Select the paragraph heading (starting with paragraph 5-4) that

best describes the nature of the 373XXAVNA system fault. Refer

to the Tableof Contents page.

2. Perform the procedure contained in the selected paragraph. In

general, the steps within each procedure should be followed in the

order presented.

3. When removing and replacing the various assemblies and compo-

nents specified by the troubleshooting procedures in this chapter,

refer to Chapter 8, Remove and Replace Procedures, as necessary.

4. If a step cannot be successfully completed, stop; correct the imme-

diate problem, and then continue on to the next step until all the

appropriate steps in the procedure are completed.

5. After troubleshooting and correcting a problem, perform the pro-

cedures in Chapter 3, (Operational Tests)and Chapter 4 (Perfor-

mance Verification),as appropriate. This should be done to insure

that the system has been fully and correctly restored to proper op-

eration.

The procedures described in this chapter provide a general approach

to troubleshooting 373XXAVNA problems. They are particularly use-

ful for problems where the 373XXAis only partially functional. The In-

ternal Diagnostic Menus described in Appendix Aare very useful for

evaluating 373XXAsystem performance. They may be used alone, or

in conjunction with the procedures in this chapter.

Please ensure you have read and fully understand the servicing con-

cepts for the 373XXApresented in Chapter 1 prior to continuing with

this chapter.
