*TST?
Syntax
*TST?
Description
This query performs a complete self-test of the instrument and returns a pass/fail indication. The self-test
runs a series of tests and will take several seconds to complete. If all tests pass, you can have a high con-
fidence that the instrument is operational.
Remarks
l The instrument self-test takes over five seconds to complete. When sending the *TST? query from the
Keysight Connection Expert 'Interactive IO' window or from the Web-based 'SCPI Command Interface'
window, it may be necessary to increase the timeout period to allow the command to complete without
error.
l If one or more tests fail, "+1" is returned and an error is stored in the error queue. For a complete listing
of the error messages related to self-test failures, see SCPI Error Messages.
l If one or more tests fail, see the KeysightKeysight 53210A/53220A/53230A 350 MHz Counter Service
Guide for instructions on obtaining service.
l Following the *TST? command, the instrument issues a Factory Reset (*RST command).
Return Format
The query returns +0 (all tests passed) or +1 (one or more tests failed).
Examples
The following example performs a self-test and returns a pass/fail indication.

Typical Response: +0
