Query Syntax

*TST? {ALL | FRAMe | SLOT{1:8}}

Description

Initiates DCA-X internal hardware self tests which are used to troubleshoot DCA-X hardware problems. Your program can send the *TST? query directly to the DCA-X or to FlexDCA on a PC that is remotely connected via the LAN to an DCA-X (Flex-on-Flex). A Flex-on-Flex connection is established using the commands in the :RDCA subsystem. The following table shows the returned values.

Returned Values

Returned Character	Description
0	All tests that were run passed.
1	At least one test failed.

Use the :SYSTem:ERRor:NEXT? query to check for errors such as a −241, "Hardware missing" when performing a test on a single slot.

Self tests are not meant to be used during normal DCA-X operation and are not available when using FlexDCA offline. In the unlikely event that your DCA-X needs service, Keysight's service team may instruct you to perform the diagnostic tests. The instrument self tests can be run from the DCA-X using the Instrument Self Tests dialog.

The following arguments can be selected:

ALL

An DCA-X frame self test is run and a module self test is run on any installed modules. If a slot is empty, no error is reported. This is the default option and is the same as sending *TST? without any arguments.

FRAMe

A self test of the DCA-X frame is executed. As this self test does not test any modules, modules do not need to be installed.

SLOT{1:8}

A module must be installed in the indicated slot before sending the *TST? query otherwise a −241, "Hardware missing" error will be reported. If a module does not support self tests in a particular slot the self test will return a "0" and the module will not be listed in the Instrument Self Tests dialog.. If a module DCA-M products that are assigned to an DCA-X slot are included in the test. If you are using a Flex-on-Flex connection, the DCA-M module will not be available.
