  • Page 29: Brief Procedures

    Brief Procedures The Self Tests use internal routines to confirm basic functionality and proper adjustment. No test equipment is required to do these test procedures. The Functional Tests utilize the probe-compensation output at the front panel as a test-signal source for further verifying that the oscilloscope functions properly. A BNC cable and a BNC-to-SMA adaptor or a TCA-SMA adapter are required to do these test procedures.

  • Page 30: Functional Tests

    Brief Procedures NOTE. If diagnostic error message 512 is displayed, run signal-path compensa- tion then re- -run diagnostic. d. Verify that no failures are found and reported on-screen.
