Otherwise, a breadboard with a couple of pots, adjustable caps, a function generator and an oscilloscope will also allow you to play with your filter values quickly (if you happen to have access to a well equipped lab).
Thank you for both of these suggestions. I have played with LTSpice a little bit, and it is very neat.

Thanks for this too, except, as diverson pointed out, we plan on going to the cRIO.
