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
option module attached.
