If Ari can reduce the signal to about one volt (voltage divider or op-amp), both sides of the BPC signal can be recorded using the 'line in' on your laptop or desktop. Most new laptops now only have a mono microphone input, so things could get complicated, but I hope this is only a challenge for Ari!
I currently use Adobe Audition to do quick and dirty analysis on sensor signals that I collect for work, but there are probably many free software programs that will allow you to look at the time signal collected from the BPC.
