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 is required to do these test procedures.
