Instrument Setup and Status IEEE-Common Commands
62 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
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 set-
ting that was active at the time the self-test query was processed. The self-test does not re-
quire operator interaction beyond sending the *TST? query.
parameters: none
response: The sum of the results for the individual tests (a 32-bit signed integer value, where 0 ≤ value
≤ 4294967296):
Bits Mnemonic Decimal Value
31 Selftest failed on Mainframe A negative value

0 Selftest failed on Slot 0 1
If 16 is returned, the module in slot 4 has failed.
If 18 is returned, the modules in slots 1 and 4 have failed.
A value of zero indicates no errors.
