Diagnostics and Calibration
The diagnostic routines provide information regarding VX4792 Arbitrary
Waveform Generator functionality. In the event of failure, these routines provide
information you can use to identify the faulty circuits. However, these routines
isolate to the functional block level only; they do not provide direct information
about failed components.
The calibration routine verifies and adjusts the basic analog calibration of the
waveform generator.
First-line service strategy for VXIbus products calls for replacement of failed
instrument modules. If a VXIbus subsystem fails, the diagnostic and calibration
routines identify the faulty module, which should be replaced. The functions
described in this section support such failure detection and correction.
For purposes of VXIbus products, the SYSFAIL~ signal asserted by an
instrument module indicates to the Resource Manager that the instrument kernel
has not passed a self-test.
A lighted front-panel FAILED indicator signifies to the user that the SYSFAIL~
signal is asserted.
