AWG2021 Service Manual
This subsection describes how to use AWG2021 internal self-test routines. No
equipment is required to do these procedures. The self tests include these internal
routines:
H Diagnostics. This self-test procedure uses internal routines to verify that the
AWG2021 functions, and passes the internal circuit tests.
H Calibration. The second procedure checks the AWG2021 internal calibration
constants and changes them if needed.
The internal diagnostic routines check AWG2021 characteristics such as
amplitude, offset, trigger level, clock, filters, X5 output amplifier, and
attenuation.
The AWG2021 automatically performs the internal diagnostics at power-on. You
can also run the internal diagnostics using the menu selections described in this
procedure. The difference between these two methods of initiating the diagnos-
tics is that the menu method does more detailed memory checking than the
power-on method.
Equipment None
Required
Prerequisites Power on the AWG2021 and allow a 20 minute warmup period before
doing this procedure.
1. Verify that internal diagnostics pass: Do the following substeps to verify
passing internal diagnostics.
a. Display the diagnostics menu and select all tests: Push
UTILITY!Diag/Cal!Diagnostics xxxx!All. See the menu in
Figure 4–1.
The list on the left shows the tests available for diagnostics. In addition
to selecting all of the tests shown for diagnostics, you can select only the
test(s) you want to run using the general purpose knob. In Figure 4–1,
the symbol to the left of Cpu indicates that test is one of the tests
selected.
