Self-test Procedures

Power-on self-test

Each time the instrument is powered on, a small set of self-tests are performed.
These tests check that the minimum set of logic and measurement hardware are
functioning properly. Any plug-in modules installed are verified for two-way
communication with the main controller. This self-test is equivalent to the
SCPI query, and you do not need to remove inputs to the instrument to run the
test. The power-on self-test takes approximately five seconds.
The following procedures shows you how to manually perform a quick instrument
