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.
