Ed, your scope readings are almost certainly the right ones. Coincidentally, I too was playing around with some servos, and checked out the waveforms on a scope and an analyzer, both were pretty consistent for a given setting.

If you have the Pickit2, why dont you confirm this by using the analyzer feature in the Pickit2 software? Thats the only analzer I have and its not let me down yet.
