Performing a Self-Test

The self-test is a series of internal tests that checks different signal generator functions. If this test fails, refer to “Self-Test Failure” on page 21 for further instructions.

Perform the following procedure to run a self-test:

1.Disconnect all external cables, including GPIB, LAN, and RS-232 cables.

2.Press Preset > Utility > Instrument Info/Help Mode > Self Test. The following message should appear:

The current status of the self-test is: Incomplete. Not all tests have been run.

3.Press Run Complete Self Test.

While the self-test is running, an activity bar is displayed on the screen indicating the test progress. If Abort is pressed while the self-test are running, the following message will be displayed:

The current status of the self-test is: Incomplete. Not all tests have been run.

When the self-test is complete, one of the following messages will be displayed:

The current status of the self-test is: Passed

The current status of the self-test is: Failure. One or more tests have

failed. System diagnostics indicate this test as the root failure: xxx

The number of tests that passed and failed are displayed in the lower left-hand corner of the display. If the signal generator fails only one test, the display shows the title of the failed test. If the signal generator fails more than one test, the test number of the most significant failure is shown.
