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 *TST?
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
self-test:
Front panel operations
1 Press [Utility] > Self Test.
2 Select Quick Test and view the result: “Self-test passed” or “Self-test failed”.
You can read errors from the error queue by pressing [View] > Errors. Refer to
DAQ970A/DAQ973A Programming Guide for a complete list of self-test errors.
Remote interface operations
1 Connect to the instrument using the remote USB interface.
2 Send *TST? and read the result: pass (+0) or fail (+1).
Use SYSTem:ERRor? to view the errors in the error queue. Refer to DAQ970A/
DAQ973A Programming Guide for a complete list of self-test errors.
