you have it right now, your analyzer is definitely not correct. I only know X4 quadrature encoders and they are very common. I do not care too much about “Position” and “rate”, because I can convert it externally, so I would focus on a basic X4 implementation. also check out the other request: > [@Quadrature Encoder Analyser](https://discuss.saleae.com/t/quadrature-encoder-analyser/877): > > Hi, I was wondering if I could get some advice on how best to interface with my Saleae Logic 16 for a project I am working on. Basically I have a stepper motor with a quadrature encoder and I am looking to characterise that motor within a mechanical system. The quadrature encoder outputs two square wave signals as shown below: [image] Basically the number of rising edges gives you the distance moved, the time between the rising edges gives you the velocity, and finally the phase of the two s… --- _[View the full topic](https://discuss.saleae.com/t/analyser-for-quadrature-encoder/2556)._
