The AWG2005 has internal diagnostics that verify circuit functionality. The
AWG2005 automatically executes the internal diagnostics at powerĆon. You
can also run the internal diagnostics by using the UTILITY menu. See
Checking Diagnostics Tests below. The difference between the two methods
of running the internal diagnostics routine is that the powerĆon method does
not do as much memory checking.
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.
Checking Diagnostics Tests
Prerequisites Ċ Power on the AWG2005 and allow a 20 minute warmup
before doing this procedure.
1. Push the UTILITY!Diag/Cal!Diagnostics
2. Select All with the general purpose knob.
3. Select Execute from the side menu. This executes all the diagnostics
automatically. As each test finishes, the result is displayed on the
screen.
4. Check the diagnostic test results. If any test failed, go to TroubleshootĆ
ing Procedure 4 Ċ Module Isolation on page 6Ć68. The table in the
flowchart shows which module is related to each diagnostic test. If the
tests pass but there is still a problem, go to the Primary Troubleshooting
Procedure on page 6Ć59.
