How do you take into account a differential signal using daqmx?

[BennyDe]

I created a channel using 2 separate voltage sources. However, both of these voltage sources are differentials across other channels on the DAQ board. Is there a way to set my physical channels as something like "differential w/ channel xxx"?

No, the differential pairs on DAQ boards are hardwired.  Generally 0-8, 1-9, etc. but that depends on the card.  Read the manual for your specific device.

Ok, so as long as I choose Differential for the "Input terminal configuration" on the "creat channel vi", I should be fine?

I am wired into the DAq board's standard differential inputs.

Yes, you should be all set.  Here's a good read on wiring considerations:  https://www.ni.com/en/shop/data-acquisition/measurement-fundamentals/field-wiring-and-noise-consider...
