8.7.12 Nth Edge Trigger
Triggers on the Nth edge that appears after the specified idle time. For example, in
the waveform shown in the figure below, the instrument should trigger on the second
rising edge after the specified idle time (the time between two neighboring rising
edges), and the idle time should be within the range between P and M (P< Idle
Time<M). Wherein, M is the time between the first rising edge and its previous rising
edge; P is the maximum time between the rising edges that participate in counting.
