in most applications. Edge trigger only detects the edges, polarities, and
voltage of signal. When the voltage of measured signal varies as identical as
the preset one (rising edge or falling edge), and the value becomes same as
trigger voltage, the oscilloscope will be triggered and capture the waveform.
[Pulse Width]
: Trigger happens when it reaches to the pulse width.
Fig. 3-5 and Fig. 3-6 show edge trigger, pulse width trigger setting interfaces.

Auto, Normal and Single are included.
Auto:
It indicates that no matter whether it meets the trigger conditions, it will
refresh the waveform in real time. In this case, the waveform displayed on the
screen seems swaying;
Normal:
Only it meets the trigger conditions can trigger be activated.
Otherwise the waveform will keep still.
Single:
In this mode, it only captures the waveform that generates for the first
time the trigger conditions are met, and then stops after finishing capture.
