Pattern Trigger (DS1000D Series)
Pattern trigger identifies trigger terms by checking appointed code. The code is
logical relationship of all channels, with high (H), low (L) and ignore(X).

Key Points:
H (High): Logic high: voltage is higher than threshold setting.
L (Low): Logic low: voltage is lower than threshold setting.
X (Ignore): Don’t care. If all the channels are ignored, the oscilloscope won’t be
triggered.
Rising Edge ( ) or Falling Edge ( ): Set the code as an edge of the channel,
rising edge or falling edge. When the edge is appointed, if code settings of other
channels are all true, the oscilloscope will be triggered on the appointed edge. If no
edge is appointed, the oscilloscope will be triggered on the last edge whose code is
true.
