Suggestions for digitizer streaming project - PXIe-5122

Spoiler
Hello All,
Spoiler
I need to work out a streaming solution for a 5122. I need to stream a "single" large record post  triggered from a 5442 AWG via the backplane. The 5122 and the 5442 will be synched via Tclock. Checking some of the more straightforward examples (Fetch Forever and Fetch Forever with a digital trigger ) seem to trick the hardware  by using the prefetch memory and prefetch arming trigger that doesn't seem to be applicable here.
Spoiler
The streaming would be at full digitizer speed (100MS/s) over a x8 MXIe link to the PC.
Spoiler
The perfect solution would have a CVI analog solution.
Spoiler
My first guess is that I will need to setup a process based on Mutli Record Fetch More than Available Memory and then compile everything back together post acquisition. I am just checking to see if I am on the right track. If so I wil head a bit farther down that road.

Hey blakney,

 

It sounds like you are on the correct path to me. That is the best example because you are going to fill up memory really quickly at those rates.
