To verify trigger sensitivity

This test verifies the trigger sensitivity. In this test, you will

apply a sine wave to the oscilloscope at the upper

bandwidth limit. You will then decrease the amplitude of the

signal to the specified levels, and check to see if the

oscilloscope is still triggered.
