Self-Test
A
power-on
self-test occurs automatically when you turn on the instrument. This
limited test assures you that the instrument and all installed plug-in modules are
operational. This self-test does
not
perform the extensive self test described
below.
A
complete
self-test actually performs a series of internal tests and takes
approximately 20 seconds to execute. If all tests pass, you can have high
confidence that the instrument and all installed plug-in modules are operational.
This feature is available from the remote interface only.
– If you have a 34951A Isolated DAC Module installed, the complete self-test
will require an additional 15 seconds to complete per DAC module (a memory
test is performed).
– The complete self-test will abort if any signals are connected to ABus1 via the
rear-panel Analog Bus connector (pins 4, 5, and 9; see
page 122). Be sure to disconnect any signals from ABus1 prior to running the
self-test.
– If the power-on or complete self-test fails, and error is stored in the error
queue. See the Keysight 34980A
Service Guide
for more information on
returning the instrument to Keysight for service.
– Following the complete self-test, the instrument issues a Factory Reset (
*RST
command).
Remote Interface Operation:
The following command returns “+0” if the
self-test is successful or “+1” if it fails.
*TST?
