Tektronix MSO58 - Trigger command group

Command groups
Trigger command group
Use the commands in the Trigger Command Group to control all aspects of
triggering for the instrument.
There are two triggers: A and B. Where appropriate, the command set has parallel
constructions for each trigger.
You c an 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 or B triggers to pulse or logic modes. With pulse triggering,
the instrument triggers whenever it detects a pulse of a certain width or height.
Logic triggering lets you logically combine the signals on one or m ore channels.
The instrument then triggers when it detects a certain combination of signal levels.
The trigger types of Pulse Width, Timeout, Runt, Window, and Rise/Fall Time can
be further qualified by a logic pattern. This is referred to as logic qualification.
