what is the best data acqusition pratice method

[Kodeeswaran]

I am using the M series DAQ devices and the while writing the applications i found that the number of samples per second is very low, just we are acquiring the data by using the parallel loops, please suggest me the best method for data acquisition.

M Series devices can acquire anywhere from 250K to 1.25 MS/sec. Which one do you have and what kind of sampling rate do you need?

I don't understand your comment about parallel loops. You only need one loop for analog acquisition. If you are also doing digital acquisition, you could have that in the same loop or in a parallel loop. Depending on which digital I/O lines you are using, that could be slow but the high speed digital is 10 Mhz I believe.

If you are getting slower rates than the above, you should post your code.
