differential using single ended mode

[astroboy]

Hi I am using the multifunction  DAS Card which is set to single end mode as I need to use it to acquire all input signals, using single end channels. Now  I have got the corrected measured inputs in RMS voltage and I would like to get the differential value from the acquired inputs, using Labview functions. So How do I go about it?

Cheers,

Clement

If all you need is the difference between one channel and another, the subtract function usually works. If it's more complicated, could explain with more details?
