NI-SCOPE (English | Japanese)

Configures the digitizer to generate a signal that other devices can detect when configured for digital triggering or sharing clocks. The signal parameter specifies what condition causes the digitizer to generate the signal. The output terminal parameter specifies where to send the signal on the hardware (such as a PFI connector or RTSI line).

In cases where multiple instances of a particular signal exist, use the signal identifier input to specify which instance to control. For normal events, only one instance exists and you should leave signal identifier set to None. You can call this VI multiple times, and set each line available to a different signal.

To unprogram a specific line on a device, call this VI with the signal you no longer want to export and set output terminal to None.

Note  This VI replaces niScope Configure Trigger Output.

Clock Out


signal identifier describes the signal being exported.


error in describes error conditions that occur before this node runs. This input provides standard error in functionality.


instrument handle out has the same value as the instrument handle.


error out contains error information. This output provides standard error out functionality.
