Pulse Width Trigger   
Pulse Width Trigger 
Trigger when < (Less than), > (Greater than), = (Equal), or ≠ (Not Equal); 
Positive pulse or Negative pulse 
Pulse Width Trigger 
Point 
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. 
Pulse Width Range  Selectable from 20ns to 10s 
 
Slope Trigger Mode 
Trigger when < (Less than), > (Greater than), = (Equal), or ≠ (Not Equal); 
Positive slope or Negative slope 
Slope Trigger Point  Equal: The oscilloscope triggers when the waveform slope is equal to the
