I'm trying to differentially measure the output of a synchro. My synchro has S1, S2 and S3 legs. Resistance readings of S1>S3 ( which I'm reading off of) are 1k ohms. I input a 5 vrms/400hz voltage on R1 to R2.
1) Does the inductance ( which I don't know) affect my reading at all?
2) Do I need to add resistors ( 47K?) to each leg of my differential input?
I'm asking because when I look on a scope it appears my DAQ is injecting noise on the other lines of my circuit. sampling at 4000 khz, 2048 samples,

Hello Clint1000,
Could you please share more information.
What DAQ do you use?
To what device you have connected and how?
Please share schematic if possible.
