Pattern Trigger (DS1000xD)
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.
Edge of appointed code
You can only appoint one code as edge. If you have appointed an edge, then
appointed another edge in a different channel, and the first appointed edge will
be set to X (Ignore).
