Self test
Pressing the Start Self Test softkey performs a series of internal procedures to
verify that the oscilloscope and any attached module are operating properly.
It is recommended you run 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.
About Oscilloscope
Pressing the About Oscilloscope softkey displays information about your
oscilloscope model number, serial number, software revision, ROM revision, and
