How to perform HSDIO with intermittant timing measurments from an external scope?

[Havarti]

I am trying to do high speed digital gen/acq with 5 pxi-6551s.  While doing the HSDIO i need to stop, setup an external tek scope to perform a timing measurement, generate 1 sample of HSDIO to cause timing even to occur, take measurment with scope, then continue with HSDIO and repeat.  Has anyone done this type of measurements before?  Any suggestions are welcome.

I am implementing this in Teststand with labview.

Thanks in advance,

Brian

In an attempt to solve this problem myself I have made the VI posted below for dynamic acquisistion and generation. The VI is supposed to generate and acquire on all 5 devices at the same time but be able to pause both acquisition and generation and wait for a software trigger.  Will the VI I made cause acquisition to wait at the same time the Generation is waiting for a script trigger?  How do you do this if not?

Brian,

The script trigger is only valid for generation so I do not believe your code will accomplish what you need.  I do not believe what you have will work.  Can you send me this VI so I can test it out?  What happend when you ran it?  Let me know and we will go from there.  Have a great day!

Thanks for the help Allen,

The VI at the time didn't run but I have since then got it to run.  I will attach it for you.  Also in my previous post i said software trigger but I meant that I would be using a script trigger to pause generation and acquisition.
