A Event Trigger Types
To Use
Click the Trigger Type button you want to
use. Set the parameters for that trigger type
in the right side of the control window.
Behavior
When you click one of the trigger icons, the
right side of the screen displays the controls
needed to use that trigger type.
The instrument provides the following trigger type categories:
Edge
triggers are the most commonly used trigger type. You can use edge triggers with
analog and digital signals. Edge triggers are available on both the Main and Delayed triggers.
Pulse
triggers are special-purpose triggers that are primarily used with digital signals. The
following classes of pulse triggers are available: Glitch, Runt, Window, Width, Transition,
and Timeout. Pulse triggers are only available on the main trigger.
Logic
triggers are special-purpose triggers that are primarily used with digital logic signals.
Two of the classes, Pattern and State, trigger the instrument based on the Boolean operator
you select for the trigger sources. A third class, Setup and Hold, triggers when data on one
trigger source changes state within the setup and hold times that you specify relative to a
clock on another trigger source. Logic triggers are only available on the main trigger.
Video
triggers are used to trigger the instrument on specified fields or lines of a video signal.
You can use one of several preset video signal formats or set a custom format.
Communication
triggers are designed to work with communication masks and standards.
Use the Trig menu
Quick Select
submenu to directly access the A Event triggers.
Sequential Triggering (Horizontal Delay On)
To Use
Select A-B Seq to use the A Event
(main) trigger with the B Event trigger
to capture complex data. The A Event
trigger arms the trigger system. The
instrument then triggers on the B Event
trigger defined by events or time. You
can also set up the instrument to delay
the B Event Trigger by a specified time
period by turning horizontal delay on.
