Hello!
I am using NI USB 6008.
In this site: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kIhASAU&l=en-ID
my NI USB 6008 does not support Analog Triggering.
What if I configure the Trigger VI in LabVIEW into Analog Trigger while my DAQ Device does not support Analog Trigger?
Thanks a lot for the answer!
I am studying the DAQ, and I am still Undergraduate students.

I would think you would get an error out of the function. You should just try it and find out!

<snark>I had done that once and accidentally opened a portal into an alternate universe, but because I had implemented adequate error handling, it closed before the aliens could come through and enslave the human race.</snark>
Sorry, couldn't resist. 😄

You should do what I do with the 6008 -- design your Analog Circuit to create a square pulse that starts at 0 v and goes (quickly) to 5 v, stays there for some time (say 0.1 ms), then comes back down to 0 v. What you've just done is to create a TTL Digital Pulse with an Analog Output channel.
I've got a 6008, and I use AO0 to generate just such a "Trigger Pulse" that I wire to one of the PFI lines that is designated as the (Digital) Trigger Input to whatever I'm trying to do.
