Hello Jos,
I first recommend that you download and extract the
LabVIEW Plug and Play driver for your instrument from IDNet into your inst.lib directory. After doing that, you should take a look at the Edge Triggered Acquisition Example from the driver and see how it works on your instrument. Then, I recommend that you see if you can the Read VI into a while loop. I am not sure how far apart your different pulse sources are, but you might have to change some of the timeout values or implement some delays in your code. Let us know how it goes.
Cheers,
