I started a project of my motorcycle that uses a toner ring and a two wire Inductive Sensor to eventually control a servo as the speedo gauge. My problem I'm having is I set up the sensor and toner ring on bench to scope the voltage produced. I'm new to using a scope and started with the rigol ds1050z. Im trying to scope the sensor at certain rpm with a specific air gap. I'm having trouble getting a clean sin wave. The voltage only amounts to 4mv at most. I would like some advice in implementing this type of sensor and scoping properly. I would really appreciate the help. Thanks
