Issue Details

I have an NI DAQ device capable of acquiring in both RSE and Differential modes. Is it possible to simultaneously acquire data from some channels in RSE and in other channels in Differential mode in LabVIEW?

Solution

Yes, you can simultaneously acquire in both RSE and Differential modes by combining two, or more, DAQmx Create Virtual Channel VI's.
As seen in the image above, doing so will allow you to configure separate channel settings within the same Analog Input task, enabling the simultaneous acquisition of RSE and Differential signals on the same device.
