For a non-JB iPad there is no WiFi analyser available; Apple pulled them. But, since you have a JB iPad I believe there are some apps available in the Cydia store. As I'm not JB I can't advise on which would be the best, so I've moved it to the Hacking section, where I think you'll receive better attention.

As an updated, I now am a user of the JB app "WiFi Analyser" and can say it is a most excellent tool!
