IF you have a DSO, can make a pulse gen then analyze the FFT of the derivative with MatchCAD, then this is for you.

Cheap high quality is $5k

Dirt Cheap is $500 I guess

Really cheap is my suggestion $50

If you dont have a DSO
Apparently Hanno says this is possible with his USB Scope. Just ask him. $199
