15.5.12 Nth Edge Trigger
Nth edge trigger is similar to an edge trigger with conditions. The trigger is satisfied after meeting the
user-defined idle time and edge number conditions. As shown in the figure below, when the idle time
between the pulse trains is greater than the specified idle time, it is triggered on the third falling edge
of the pulse train.
Trigger source, slope (rising, falling), idle time, and edge number can be set in the trigger dialog box.
Holdoff, coupling, and noise reject can be set in the Nth edge trigger, see the sections "Holdoff",
"Trigger Coupling" and "Noise Reject" for details.
