If you set this attribute to Disabled, the Reference Triggers bypass the OSP block and are processed immediately.

Enabling this attribute requires the following equipment configurations:

  • All digitizers being used must be the same model and hardware revision.  

  • All digitizers must use the same firmware.  

  • All digitizers must be configured with the same I/Q rate.  

  • All devices must use the same signal path.  

For more information about the digitizer OSP block and Reference Triggers, refer to the following topics in the NI High-Speed Digitizers Help:

You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.

The default value is Enabled.
