Step 4. Faulty Group Isolation

Step 4. Faulty Group Isolation
Use the following procedures only if you have read the previous sections in this chapter
and you think the problem is in the analyzer. These are simple procedures to verify the
four functional groups in sequence, and determine which group is faulty.
The four functional groups are:
• power supplies
• digital control
• source
• receiver
Descriptions of these groups are provided in Chapter 12 , "Theory of Operation."
The checks in the following pages must be performed in the order presented. If one of the
procedures fails, it is an indication that the problem is in the functional group checked. Go
to the troubleshooting information for the indicated group, to isolate the problem to the
defective assembly.
Figure 4-3 illustrates the troubleshooting organization.
