VX4101A MultiPaq Instrument User Manual
488.2 commands can be used to run more extensive self-tests of instrument
specific functions. During the interface test, or during a hard or soft reset, the
following actions take place:
1. The backplane SYSFAIL* line is asserted, indicating that the module is not
ready for communication.
2. A test of the VXIbus interface logic is performed.
3. Each instrument is configured to its *RST initial state.
4. On successful completion of the interface test, the backplane SYSFAIL* line
is negated and the VX4101A enters the VXIbus PASSED state (ready for
normal operation). If the interface test is not successful, the backplane
SYSFAIL* line remains asserted and the VX4101A enters the VXIbus
FAILED state.
Instrument Self-Tests. Instrument specific self-tests can be run at any time during
normal operations. To run self-test solely on the active instrument, send the
TEST:ALL? query. To test all instruments on the VX4101A, send the *TST?
query. See the instrument specific Syntax and Commands section for each
instrument for more detailed information on each self-test.
During a commanded self-test:
1. The backplane SYSFAIL* line is not asserted.
2. At the end of a successful instrument self-test, the instrument is placed in its
*RST (power-on) configuration.
3. At the end of a successful *TST?, the entire VX4101A will be placed in its
*RST (power-on) state.
Operational Check
This section tells you how to do an operational check of the VX4101A instru-
ments using the soft front panel (SFP). Depending on the configuration you have
purchased, the operational check includes the following procedures:
H Standard configuration
