How to collect data for every rising edge?

[University guy]

I need to collect the data for every rising edge a trigger perfoms. So far I could collect the data but it seems that it only collect the data in the start of triggering, but not continuously. I also want to put the data in an excel spreadsheet and automatically add new set of data when the next rising edge occur.

I have ni usb-6211 data board, external trigger signal (square wave) in port PFI0 and three analog inputs (voltage).

Thanks for every help!

You have to specify your TTL signal as the external sampling signal. See attached.
