Trigger Overview

NOTE: Trigger capabilities on channel 1-4 (i.e., the first acquisition
module) are more complete than on channels 5 or higher. Full Edge
trigger bandwidth is available on all channels, but SMART triggers are
not available on Channel 5 or higher.
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.
