Using Logic Triggering
Logic triggering is available when Logic is selected for pulse input
channels (p. 61).
Triggering is controlled by the signal state and combination of
logic input signal channels.
Select a trigger pattern (1, 0, or X) and AND/OR combining logic
so that triggering occurs when the combined criteria are satisfied.
Make trigger settings on the [CH] screen.
See:"Key Setting Procedure" (p .101)
