STS?
STS? –
might return the value 5, which means the Preselector is using
filter 5.
*TST? (Self-Test) runs the Preselector's internal self-test and reports the results.
The self-test does not require operator interaction. Upon completion of *TST?,
the Preselector returns to the state it was in just prior to the self-test.
*TST?
The test response is either 0 (no errors detected) or non–zero (a micro-processor
error). Send the Preselector to the nearest Tektronix servicing center if the test
response is not zero.
*TST? –
might return the value 220, showing that several microprocessor
logic lines are not working properly.
The *WAI (Wait-to-Continue) command prevents a GPIB device from executing
further commands or queries until all pending operations finish. You do not need
to use *WAI in your programs; because the Preselector executes commands
sequentially, the *WAI command continues immediately.
Related commands: *OPC, *OPT.
