c.
Setup & hold
：

(4) Time
Compare the setup, hold time of code with the setting time of
△
T,
it will be triggered when the
condition is met. The range can be set 8ns ~ 10s.
7.12 Nth Edge Trigger
The Nth edge trigger is triggered on the Nth edge after the specified idle time. For example, as shown in
Figure 7-9, it is set to trigger on the 2nd rising edge after the specified idle time (the time between two
adjacent rising edge), then set the idle time as P
＜
idle time
＜
M, M is the time between the 1st rising
edge and the next rising edge, P is the maximum time between the counting rising edge.

It can select rising edge, falling edge. The
current slope is displayed in the upper right corner of the screen.
a. Rising edge: Set to trigger on the rising edge of the signal.
b. Falling edge: Set to trigger on the falling edge of the signal.
