Main > Time > Trig Delay
Description:
Set the trigger delay time in seconds with respect to the trigger. Positive values cause the
actual trigger to occur after the trigger condition is met. This places the trigger event to
the left of the trigger point on the display, and is useful for viewing events during a pulse,
some fixed delay time after the rising edge trigger. Negative trigger delay places the
trigger event to the right of the trigger point on the display, and is useful for looking at
events before the trigger edge.
