To run the internal self-tests
To run the internal self-tests
Self Test performs a series of internal procedures to verify that the oscilloscope
and any attached module are operating properly.
It is recommended that you run the Self Test:
• after experiencing abnormal operation
• for additional information to better describe an oscilloscope failure
• to verify proper operation after the oscilloscope has been repaired
Successfully passing Self Test does not guarantee 100% of the oscilloscope’s
functionality. Self Test is designed to provide an 80% confidence level that the
oscilloscope is operating properly.
