Analog Discovery 2 Specifications

Turn your PC into a powerful circuit learning platform that can measure, visualize, analyze, record, and control mixed signal circuits! The Analog Discovery 2 is small enough to fit in your pocket and it costs less than a textbook, but it is powerful enough to be the centerpiece of a world-class circuits or electronics teaching lab. Powered by a Hi-Speed USB port and the free WaveForms software, the Analog Discovery 2 lets you build and test analog and digital circuits anywhere you want to work, even outside of the lab.
