The Digilent Digital Discovery is a compact and versatile USB device that functions as a logic analyzer, protocol analyzer and digital signal generator. It offers up to 32 channels with selectable sampling rate (8 channels at 800 MS/s, 16 at 400 MS/s, 32 at 200 MS/s), supports logic levels between 1.2 V and 3.3 V and programmable current sources. With the optional high-speed adapter and impedance-matched probes, high-speed signals can be reliably measured. The free WaveForms software enables logic analysis, pattern generation, virtual digital I/Os, protocol decoding and is compatible with Windows, macOS and Linux.
