Chapter 5 Troubleshooting

5-1

5-2

INTRODUCTION

This chapter provides specific procedures to be followed when trouble-

 

shooting 373XXA VNA systems. While performing these procedures, al-

 

ways observe the warnings and cautions on the opposite page.

 

To use the troubleshooting procedures in this chapter:

 

1.

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

 

 

best describes the nature of the 373XXA VNA system fault. Refer

 

 

to the Table of 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 373XXA VNA problems. They are particularly use-

 

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

 

ternal Diagnostic Menus described in Appendix A are very useful for

 

evaluating 373XXA system 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 373XXA presented in Chapter 1 prior to continuing with

 

this chapter.
