7.4 Self test
An internal self-test can be performed over the bus by sending the *TST? query command. The self-
test will run until the first error is encountered and terminate. The response to the query will either be
the first error encountered or 0 if no error was found (Self-test passed).
To execute a self-test, the IEEE-488, LAN, RS232 or USB interface must be used. The iXCGui
command self-test window can be used to send the *TST? Command. See the section 9 for possible
self test error codes and messages.
Note that the internal selftest is more comprehensive than the power on memory test that always runs
when the unit is turned on. The memory test only checks the integrity of the controller and its non-
volatile memory content. The self test runs an actual power test on all amplifiers.
