VXi VT1529A/B 사용자 설명서

For a quick functional check of the VT1529A/B, perform only the 
VT1422A Self-Test.

The VT1422A VXIplug&play Soft Front Panel can be used to enter the 
commands and queries described in the test procedures.

This test performs a self-test on the VT1529A/B by running the VT1422A 
self-test. This self-test checks much of the basic functionality of the 
VT1529A/B.

The VT1529A/B must be connected to the VT1422A through the VT1539A 
SCP. The dummy load is not required for this test, but may be connected.

Send the DIAG:TEST:REM:SELF? (@<ch_list>) query to the VT1422A 
module. The expected return value is “+0”.

One problem with the current VT1422A drivers is that a failure on one 
channel will can cause the VT1422A to report that all channels failed. This 
can make it difficult to find the channel that is failing. It may be easiest to 
let all the tests run and then look at the channels with the most failures.

See “DIAGnostic:TEST:REMote:SELFtest?” on page 288 for details on the 
self-test, return values and possible causes.

This test performs a calibration of the VT1529A/B by running the VT1422A 
remote calibration command. The calibration sequence checks the results 
for reasonable values and reports errors.

This test requires that the time since the last *CAL? calibration be less than 
8 hours. The test program (perf_e1529.c) insures this by forcing a *CAL at 
the beginning of the program.

The VT1529A/B must be connected to the VT1422A through the VT1539A 
SCP. The dummy load is not required for this test, but may be connected.

If necessary, send the *CAL? query to the VT1422A (required if more than 
8 hours has elapsed since the last *CAL? command). The expected return 
value is “+0”.

Send the CAL:REMote? (@<ch_list>) query to the VT1422A module. 
The expected return value is “+0”.
