How To Use Start Trigger Function with NI-SCOPE

How to use the "Start trigger" function with NI-SCOPE just like in DAQmx? I tried to use "niScope Configure Trigger (poly)" but it did not work as I expected.

I want to do a continuous measurement with a NI-SCOPE card that is started by a start trigger. How do I implement this?

You are not able to specify a "Start Trigger" directly with the NI-SCOPE API. If you want to do so, you'll need to use NI-SCOPE property node instead of API. The image below show the property node that allows you to specify the start trigger source.

LabVIEW provides some NI-SCOPE examples, which you can use for quick development. Below is a modified version of the example "niSxope EX Fetch Forever.vi". It uses an external signal on PFI1 as a start trigger.
