VX4792 User Manual
In many instances, the front-panel indicators provide sufficient information to
identify an instrument module failure. A red-lighted indicator signifies that the
CPU is inoperative.
Diagnostic routines for the waveform generator consist of the CPU test, setup
test, and waveform test. These routines run automatically at power-on. You can
invoke these diagnostics at any time with the command.
The CPU test routine verifies that the processor and ancillary circuits are capable
of supporting the operating system.
The setup test and waveform test routines verify that the waveform generator
hardware is capable of proper operation.
. The instrument immediately reports module failures by lighting the
front-panel FAILED indicator and by asserting the VXIbus SYSFAIL~ signal.
The self-calibration routines run automatically at power-on. You can obtain
maximum accuracy from the waveform generator by performing a self-calibra-
tion (using the query) just before use.
The commands and queries listed in Table 2–6 are used for diagnostics and
calibration. Refer to Syntax and Commands for detailed descriptions of each
command.
