Trigger
NOTE : Channels 1-4 have complete triggering capability for Edge, SMART and
other triggers. Channels 5 or higher have more limited edge trigger bandwidth and
do not support SMART or other triggers. Refer to LabMaster specifications on

Triggering is the way an oscilloscope selects an exact moment in time on a
signal to then be shown on the screen. If the pattern of a signal happens to
be repetitive, a continuous waveform pattern is inherently visible on the
display.
But without a regular signal pattern, the oscilloscope requires controls to
determine what specific point in time (when a trigger is met) to show the
signal on the display. This is accomplished and affected in a variety of ways.
Some trigger settings allow for pre-trigger, post-trigger, and a delay
between the time of the trigger event and the time when the display is
refreshed (or sweeped) and the waveform is again shown on the screen.
The instrument uses many waveform capture techniques that trigger on
features and conditions that you define. These triggers fall into the
following major categories:

Simple Triggers - activated by basic waveform features or conditions
such as a positive or negative slope, and hold‐off

SMART Triggers - sophisticated triggers that enable you to use basic
or complex conditions for triggering. Use SMART Triggers for signals
with rare features, like glitches.

Measurement Trigger - triggers that allow you to leverage
parameter measurements as waveform trigger conditions. A
measurement trigger is either the only trigger or the final trigger in a
chain of trigger events including hardware triggers.

MultiStage Triggers - varied forms of triggers including Cascaded,
QualFirst, and Qualified allowing varied combinations of triggers
and trigger stages.

Serial Triggers - provide serial data protocol specific triggering for a
wide variety of standards.
