Stephan, I had a quite similar problem some time ago - it was discussed in this list.. The best solution turned out using hardware synchronization of digital/DAC output to trigger line of ADC is an easiest way.. However, the major question is- how much time is actually allowed between "simultaneous" events.. Couple of microsecond is the best you can really expect from general purpose DAQ systems..
