Analog Discovery Pro from Digilent comes in a 2-channel (ADP3250) or 4-channel (ADP3450) version. These all-in-one instruments work with a PC over USB or can run entirely standalone. On the PC the excellent Waveforms software provides virtual instruments like an Oscilloscope, Logic Analyzer, Power Supply, Spectrum Analyzer, Curve Tracer, Network Analyzer, and Impedance Analyzer. Just to name a few. See what this new instrument offers in this hands-on review. This episode was sponsored by Digilent.
