Field Rates, Video
Trigger Type
Supports NTSC, PAL and SECAM
broadcast systems for any field or
any line
Holdoff Range 100ns to 10s
Pulse Width Trigger
Pulse Width Trigger
Mode
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.
