I'm using a MID-7604 stepper motor driver. I'd like to reduce the ground loop noise in the system that I am measuring on my PXI-5152 (through a series of transducers, etc.) by using an optical or transformer isolator for the 68 pin VHDCI cable that connects the motor driver to the computer. Does such a thing exist or are there other methods to mitigate the noise? I'd prefer to have the MID-7604 and the computer connected to the same circuit/I don't really want to buy a gigantic isolation transformer/surge protector just to plug in the MID-7604.
