This section describes the basic troubleshooting procedural
flow when servicing the E4982A. The primary procedural
tool in this section is the flowchart. The flowchart contains
the entire troubleshooting path from the failure symptom to
the isolation of faulty assembly, and will direct you through
the repair in an orderly manner through the possible failure
symptoms. Reference letters (Yes/No) on the flowchart point
to procedural steps that briefly explain the next
troubleshooting method to be performed.
The primary trouble isolation procedure can be performed
without disassembling the E4982A.
