Configure Trigger (Configure Digital Edge Reference Trigger) (G Dataflow)

Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

The specified trigger source.

You can choose PFI <0..3>, PFI <24..31>, PXI Trigger Line/RTSI <0..7>, PXI STAR Line, or PXIe DStarB.

Note

Only the PXIe-6555/6556 devices support PFI <24..31> and PXIe DStarB.

The specified edge to detect.

Default: Rising edge

The number of pretrigger samples the device must receive before the Reference trigger is acknowledged.

Default: 500

Handle that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.
