Self Test Errors
The 34450A self test (see the *TST? command) performs a series of
tests on the instrument hardware. Any failure of these tests will generate
a SCPI error number - 330, with additional test failure information. Refer
to the Keysight 34450A Programmer’s Helpfile for more information.
The form of this error message is as follows:
- 330,"self test failed; <test# - testname>"
Where test# is the number of the test that failed (range 600 - 607) and
testname describes the test. Here is an example of a test failure message:
- 330,"self test failed; 602 – M/B flash failed"
The following is the list of test numbers and descriptions:
NOTE
On the remote interface, a self–test failure will generate SCPI error –330 and a
supplemental message indicating one of the test numbers shown below. On the front
panel, only the failing test is shown.
