Remote testing

To invoke the remote self test, the IEEE 488.1 compliant standard command,
*TST? is used. This command runs a full self test and returns one of the following
codes:
– 0 - no tests failed
– 1 - one or more tests failed
The remote self test consists of the following tests:
The communications assembly is tested implicitly, in that the command will not
be accepted or return a result unless the remote interface is functioning correctly.
Refer to
individual test.
When the *TST? command is executed, the screen is cleared. As each test takes
place, the name of the test is listed on the screen. While a test is running, the
message Testing... appears beside the name of the test. As each stage of the test
is completed, the message Testing... is replaced by either the message Passed or
Failed.

Test descriptions

This section specifies what is actually checked by each of the tests. Some of the
tests may only be applicable to one method of invocation (for example, from the
front panel). If this is the case, it is specified in the test description. Most of the
tests have an associated error message which is added to the error queue if the
test fails. The exception to this is the bitmap display test. Refer to
Messages"
