select the channel, or rotate the Entry knob or the Select knob.
Then, press one of these softkeys to set the condition the

X to ignore this channel
Rising or falling edge
Specifying an Edge in a Pattern
You are allowed to specify only one rising or falling edge term in the pattern. If
you define an edge term, then select a different channel in the pattern and
define another edge term, the previous edge definition is changed to a don't
care.
Source Definitions for Simple Pattern Trigger Affect Advanced Trigger
The source definitions for the simple pattern trigger are shared with the
Pattern 1 and Edge 1 source definitions of the advanced pattern trigger
specification. Thus, changes to the simple pattern trigger will affect that
specification, and changes to Pattern 1 and Edge 1 in the advanced trigger
specification will affect the regular pattern trigger. Defining patterns for the two
trigger types differs. See "To define an advanced pattern trigger."
