Good question.

How many RISING edges per channel per rev?
Also, how well are the falling edges positioned wrt the rising edges (how close to 50% duty cycle is it?)
Finally how well are the two channels oriented (90 degree being optimal -- thus quad in the name)?

Dr. Joe J.

P.S. Can you share a screen shot of an o-scope trace of the two signals?

P.P.S. Can you provide some photos of the sensor assembled on the motor?
