Use the commands in the Trigger Command Group to control all aspects of
triggering for the oscilloscope.
There are two triggers: A and B. Where appropriate, this command set has parallel
construction between triggers.
You can set the A or B triggers to edge mode. Edge triggering lets you display
a waveform at or near the point where the signal passes through a voltage level
of your choosing.
You can also set A triggers to pulse, logic, or video modes. With pulse triggering,
the oscilloscope triggers whenever it detects a pulse of a certain width or height.
Logic triggering lets you logically combine the signals on one or channels. The
oscilloscope then triggers when it detects a certain combination of signal levels.
Video triggering enables you to trigger on the most common Standard Definition
video standards.
