How to synchronize NI-Scope and traditional DAQ

[Thomas Bruns]

I use a PXI-1042 System with a PXI-5124 Ni-Scope Card and a PXI-6120 with traditional DAQ controlled by a PC running WinXP and LabView 7.0
The intention of this setup is to make synchronized acquisition with both cards with different sample rates. For the sake of an example let's assume the NI-Scope runs at 100MS/s and the DAQ (6120) with 100kS/s. The Trigger is generated by analog triggering of the 6120. I'm looking for a solution to garanty that for a STOP trigger with post-trigger scans the last sample of the 6120 coincides in time with the last sample of the NI-Scope 5124 card.
Or to put it in more general terms a way to identify which of the 1000 Samples the 5124 Card takes in the sample interval of the 6120 coincides with the respective sample of the 6120 ? The point is to have a time resolution (for phase difference measurements) better than that given by the samplerate of the PXI-6120.

Here you can find an example that shows how to synchronize a DAQ-Device with a Scope-card:

Hope this helps.
