command:
*TST?
syntax:
*TST?
description:
The self-TeST query *TST? makes the instrument perform a self-test and place the results of the test in the output queue. If
the self-test fails, the results are also put in the error queue. We recommend that you read self-test results from the error
queue. No further commands are allowed while the test is running. After the self-test the instrument is returned to the
setting that was active at the time the self-test query was processed. The self-test does not require operator interaction
beyond sending the *TST? query.
