Re: Arbitrary Quadrature Encoder
Yes, the limiting factor would be the phototransistors. It is about three times slower compared to the op-amp. The phototransistor only needs to trigger the hysteresis, which can be slightly reduced. The theoretical peak of the phototransistor would then match the capabilities of the op-amp.
Theoretically, the encoder can go faster than the cRIO can handle but it does not even come close to what the jaguar can handle. For the Jaguar case the op-amp and the phototransistor are the limiting components.
