Self Tests
This subsection describes how to use AWG2005 internal selfĆtest routines.
No equipment is required to do these procedures. The self tests include
these internal routines:
H Diagnostics
This selfĆtest procedure uses internal routines to verify that the
AWG2005 functions, and passes the internal circuit tests.
H Calibration
The second procedure checks the AWG2005 internal calibration
constants and changes them if needed.
The internal diagnostic routines check AWG2005 characteristics such as
amplitude, offset, trigger level, clock, filters and attenuation.
The AWG2005 automatically performs the internal diagnostics at powerĆon;
you can also run the internal diagnostics using the menu selections deĆ
scribed in this procedure. The difference between these two methods of
initiating the diagnostics is that the menu method does more detailed
memory checking than the powerĆon method.
Equipment Required: None.
Prerequisites: Power on the AWG2005 and allow a twentyĆminute warmup
period before doing this procedure.
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 4Ć1.
The Diagnostics column on the left shows the tests available for
diagnostics. In addition to selecting all of the tests shown for DiagĆ
nostics, you can select only the test(s) you want to run using the
general purpose knob. In Figure 4Ć1, the symbol to the left of Cpu
indicates that test is one of the tests selected.
