Video is not a type of trigger in a Digital Storage Oscilloscope (DSO):
·
Pulse width trigger
Triggers on pulses with a specified width range. This can be used to find glitches, rare events, or extreme values in PWM signals.
·
Level trigger
Triggers when the voltage exceeds a threshold value. The trigger level is displayed as a horizontal line.
·
Edge trigger
Triggers on the first occurrence of a rising or falling voltage. The trigger voltage level and direction can be set. Edge triggering is often used to capture periodic waveforms or debug electronic circuits.
