Hello,
For future references, the correct place to post questions about the NI 4472 is the Dynamic Signal Acquisition (DSA) board, not the Multifunction DAQ board.
One of our DSA systems engineers ran some tests using a 100-ft RG-62 cable (like this one) to provide sensor connectivity to a DSA device and had no problems with signal degradation. I would recommend this cable for your application. Let me know if you have any questions about this.
As far as general information on what you need to take into consideration when measuring analog signals, check out Field Wiring and Noise Considerations for Analog Signals. I'm not sure if this is what you were looking for, so let me know if you need to know something more specific.
I hope this helps!

Hello,
I doubt there will be any problems just because it is not the exact cable recommended by the manufacturer. I recommended it because it worked well in tests conducted with our DSA devices. I don't know of a specific cable with those exact specifications (20 AWG, twisted pair) and I think the RG-62 is similar enough that it really won't make a difference.
