PicoScope 7 Software
Available on Windows, Mac and Linux
Quadrature encoding is used by rotary position sensors to transmit information about the angle and direction of a roating shaft, for example on a motor or a control dial, as a pair of binary signals. Now you can decode these signals just by downloading a free copy of PicoScope 6.14.48 or later.
PicoScope displays the decoded information in the same window as the raw signals so you can analyze timings and spot any problems. It's easy to set up: just go to Tools > Serial Decoding and choose Quadrature as the signal format.
