The output of synchros are phase shifted AC signals between pairs of poles. You need just two of these signals. What you can do is sample two legs with two channels of a DAQ card. You can then measure the phase angle in real time with "Extract Single Tone" node (wave operations toolbox) You will need to build two identical channels. The relative phase out of the phase port of the two Extract Single Tone nodes will be proportional to your position.
I'd be happy to work with you on this. I'm one of the few old geezers left who knows what a syncho is!
