This topic has been touched on for other cards, but I am hoping someone can tell me if this is possible using M-Series, namely PCI-6251. I need to acquire an analog input and also a digital 16-bit port both at 1MHz synchonously. I have been trying to set up a simple digital acquire at 1Mhz in DAQmx, but it isn't as straighforward as an analog input. For digital I can't simply specify the "sample rate" like I can in analog. Do I need to set up a 1MHz counter or something and trigger the analog and digital inputs off the counter? Hopefully someone can let me know if I am going in the right direction on this... This seems like the quintescential "mixed signal" application that one would think the multifunction M-Series would be ideal for, but I haven't found any high speed digital acquisition example vi's.

Can I aquire Digital input and analog input simultaneously using M-Series in Labview?

Hello Alan and Billings11,

Thanks for the replies (even though the discussion closed a few months ago). Things have been clearified for me. Now I have to convince the projectmanager to buy a new M-series card :-))

PS Even NI tech support didn't understand correlated or waveform capabilities of the hardware (as quoted from the users manual)...
