Chapter 6Removal and ReplacementProcedures

6-1 INTRODUCTION This chapter provides procedures for gaining access to the major

682XXB/683XXB assemblies, subassemblies, and components for

troubleshooting or replacement.

WARNING

Hazardous voltages are present inside the 682XXB/683XXB

whenever ac line power is connected. Turnoff the unit and

remove the line cord before removing any covers or panels.

Troubleshootingand repair procedures should only be per-

formed by service personnel who are fully aware of the po-

tential hazards.

CAUTION

Many subassemblies in the signal generator contain static-

sensitive components. Improper handling of these subas-

semblies may result in damage to the components. Always

observe the static-sensitive component handling procedures

described in Chapter 1, Figure 1-4.
