AWG2021 Service Manual
This subsection contains information and procedures designed to isolate faulty
modules in the AWG2021 Arbitrary Waveform Generator. If these procedures
indicate a module needs to be replaced, follow the Removal and Installation
Procedures in the preceding subsection.
After replacing a module, do the adjustments in section 5, Adjustment Proce-
dures (page 5–1).
The troubleshooting procedures in this subsection consist of these flowcharts.

Module

To use these procedures, begin with the Primary Troubleshooting Procedure. It
prompts you to check various indications of AWG2021 functionality and directs
you to the other troubleshooting procedures.
The AWG2021 has internal diagnostics that verify circuit functionality. The
AWG2021 automatically executes the internal diagnostics at power-on. You can
also run the internal diagnostics by using the UTILITY menu. See Checking
Diagnostics Tests on page 6–54. The two methods of running the internal
diagnostics routine are the same, but the power-on method does a less extensive
memory check.
If the internal diagnostics indicate a test in the internal diagnostics failed, use the
troubleshooting procedures in this subsection to determine which module to
replace.
