Trigger when < (Less than), > (Greater than), = (Equal), or ≠ (Not Equal);
Positive pulse or Negative pulse
Equal: The oscilloscope triggers when the trailing edge of the pulse
crosses the trigger level.
Not Equal: If the pulse is narrower than the specified width, the trigger
point is the trailing edge. Otherwise, the oscilloscope triggers when a
pulse continues longer than the time specified as the Pulse Width.
Less than: The trigger point is the trailing edge.
Greater than (also called overtime trigger): The oscilloscope triggers
when a pulse continues longer than the time specified as the Pulse
Width.
