Output(s)

Description

A device can have one or more device trigger outputs, usually available as pins on an extension connector on the instrument. The trigger outputs are controlled by events that occur in the instrument.

Use the function DevTrGetOutputCount() to determine the amount of available device trigger outputs. To use a device trigger output, use the function DevTrOutSetEnabled() to enable it.

Modules
	Enabled
	The enabled state of a device trigger output determines whether an output is used.
	Event
	Select the event that controls the trigger output.
	Info
	Obtain information of a device trigger output.
