Issue Details

Is it possible to generate differential analog output using NI 7868 FPGA card?

Solution

As is mentioned in the specification sheet of the 7868 card, AO supports only the single ended mode of voltage generation. The pins corresponding to this are AO and AOGND.

With cards that support only single ended lines, the work around is to use two single ended lines to get the required +/- voltage levels.
