Using the Oscilloscope

The Scope Trigger Menu

Count field

The Count field defines the number of trigger events that must occur

after the first trigger qualifier before the oscilloscope will trigger and

acquire a waveform. In edge trigger mode, you can define a positive or

negative edge and the trigger level as a trigger qualifier. When the

oscilloscope detects the trigger qualifier, it will trigger at a user-

specified number of edges (Count field) on the waveform. Count can

be set to any integer from 1 to 32,000.

This type of triggering is commonly referred to as "events triggering" or

"delay-by-events triggering". It is very useful when trying to trigger on a

specific pulse in a burst of pulses, with a long time delay, before the

next burst occurs.

The default value for the Count field is 1.
