7.Timeout Trigger
The oscilloscope triggers when the time interval from when the rising edge (or the
falling edge) passes through the trigger level to when the neighbouring falling edge
(or the rising edge) passes through the trigger level is greater than the timeout time
set.
In Timeout Trigger mode, the trigger setting information is displayed on bottom right
of the screen, for example, ，indicates that trigger type is Timeout,
trigger source is CH1, edge is positive, 0.00mV is up level or low level threshold.

Start timing when the rising edge of the input signal
passes through the trigger level.
Start timing when the falling edge of the input signal
passes through the trigger level.
Configure Idle Time
Set idle time. Idle time means the minimum time of idle
clock before searching data that can meet trigger
conditions. Available range is 30ns-10s, default 100ns.

Acquire waveform when trigger occurred
When trigger occurs, acquire one waveform then stop
100 ns - 10 s, adjust M knob or click to set time
interval before another trigger occur, press
panel button or click move cursor to choose
which digit to be set.
Set Holdoff time as 100 ns
8.Nth Edge trigger
The oscilloscope triggers on the Nth edge that appears on the specified idle time. As
figure shown below, the oscilloscope should trigger on the second falling edge after
the specified idle time and the idle time should be set to P1/P2/P3/P4 < Idle Time < M.
Wherein, M, P1, P2, P3 and P4 are positive or negative pulse width participating in
the counting.
