Chapter 6 — Troubleshooting

6-1

Introduction

This chapter provides information about troubleshooting tests that can be used to check the ME7838 Series
VNA System for proper operation. These tests are intended to be used as a troubleshooting tool for identifying
the faulty system components and checking the functionality of internal components and sub-assemblies in the
3739A, 3739B and 3739C Broadband Test Sets.

6-2

General Safety Warnings

Many of the troubleshooting procedures presented in this chapter require the removal of instrument covers to
gain access to subassemblies and modules. When using these procedures, please observe the warning and
caution notices.

Warning

Hazardous voltages are presented inside the instrument when AC line power is connected. Before
removing any covers, turn off the instrument via the Main power switch on the front panel and unplug
the AC power cord.

Caution

Many assemblies and modules in the 3739X Test Set contain static-sensitive components. Improper
handling of these assemblies and modules may result in damage to the assemblies and modules.
Always observe the static-sensitive component handling precautions.

Caution

To provide protection for the rear panel connectors, when the top cover is removed, the rear feet
should be reattached onto the chassis after removing the top cover.
