The SADI is a data acquisition and control platform designed to interface with National Instruments’ LabView software.  With the SADI, analog, digital or quadrature encoder signals can be read and reported live to a PC connected over USB at frequencies up to several kHz.  The SADI can also be used to output analog and digital signals (including PWM and PCM type waveforms) using LabView.
