Self Tests

Diagnostics

This subsection describes how to use AWG2005 internal self/test routines. No equipment is required to do these procedures. The self tests include these internal routines:

￿Diagnostics

This self/test procedure uses internal routines to verify that the AWG2005 functions, and passes the internal circuit tests.

￿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 power/on; you can also run the internal diagnostics using the menu selections de/ 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 power/on method.

Equipment Required: None.

Prerequisites: Power on the AWG2005 and allow a twenty/minute warmup period before doing this procedure.

Procedure:

1.Verify that internal diagnostics pass: Do the following substeps to verify passing internal diagnostics.

a.￿isplay the diagnostics menu and select all tests: Push UTILITY￿Diag/Cal￿Diagnostics xxxx￿All. See the menu in Figure￿4/1.

The Diagnostics column on the left shows the tests available for diagnostics. In addition to selecting all of the tests shown for Diag/ nostics, 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.
