*TST? (Self-Test Query)
The *TST? self-test query causes the Test Set to execute a series of
internal self-tests and place a numeric response into the Output Queue
indicating whether or not the Test Set completed the self-test without
any detected errors. The response data is obtained by reading the
Output Queue into a numeric variable, real or integer. Upon successful
completion of the self-test the Test Set settings are restored to their
values prior to receipt of the *TST? command.
NOTE Refer to the Test Set’s Assembly Level Repair manual for further
information on Power-Up Self Test Failure.
