Trigger
The Trigger function configures the conditions by which the
oscilloscope captures the incoming signals.
Trigger type
Edge
Triggers when the signal crosses an amplitude
threshold in either a positive or negative slope.
Video
Extracts a sync pulse from a video format signal
and triggers on a specific line or field.
Pulse
Triggers when the pulse width of the signal
matches the trigger settings.

Trigger mode
Auto
The oscilloscope updates the input signal
regardless of the trigger conditions (if
there is no trigger event, the oscilloscope
generates an internal trigger). Select this
mode especially when viewing rolling
waveforms at a slow timebase.
