Legion ADC HD

128-Channel Analog-to-Digital Converter

Legion ACD HD


The LEGION ADC offers fully parallel operation for simultaneous data acquisition from all channels without multiplexing in an ultra-compact external USB enclosure. Each unit supports 128-element detectors. It was designed by PhotoSound for massively parallel data acquisition utilized in photoacoustic, laser-induced ultrasound, and X-ray acoustic real-time imaging applications.
