Configure Trigger (Digital) (G Dataflow)

Last Modified: April 2, 2018

Configures the common properties of a digital trigger.

connector_pane_image
datatype_icon

trigger slope

The trigger edge on which to trigger the digitizer.

datatype_icon

session in

Handle that identifies the NI-SCOPE instrument session as previously allocated by Initialize With Options.

datatype_icon

error in

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

datatype_icon

trigger source

The source you want the digitizer to monitor for a trigger.

Name Description
Channel 0 Monitors Channel 0 for a trigger signal.
Channel 1 Monitors Channel 1 for a trigger signal.
Channel 2 Monitors Channel 2 for a trigger signal.
Channel 3 Monitors Channel 3 for a trigger signal.
Channel 4 Monitors Channel 4 for a trigger signal.
Channel 5 Monitors Channel 5 for a trigger signal.
Channel 6 Monitors Channel 6 for a trigger signal.
Channel 7 Monitors Channel 7 for a trigger signal.
External TRIG Monitors an external trigger input for a trigger signal.

Default: Channel 0

datatype_icon

trigger holdoff

The length of time the digitizer waits after detecting a trigger before enabling NI-SCOPE to detect another trigger.

Default: 0.00

datatype_icon

trigger delay

The length of time the digitizer waits after it receives the trigger to start acquiring data.

datatype_icon

session out

Reference to the NI-SCOPE instrument session to pass to the next node in the program.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
