Legion ADC HD - Base Unit

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 massive parallel data acquisition utilized in photoacoustic, laser-induced ultrasound and X-ray acoustic real-time imaging applications.

Features

• Compact, durable and light enclosures with integrated cooling fans
• Streaming ADCs for continuous data acquisition with no buffering or multiplexing
• Each analog channel has an integrated amplifier with digitally controlled gain
• Acoustoelectrics
• Generate trigger output at defined rate or repetition of external trigger input with programmed delay
• Connect up to four units in parallel and acquire more data at fast data acquisition rates
• Sync external hardware with data acquisition using electronic or optical IN/OUT ports
• Standalone control software based on MATLAB, open SDK written in C# and access to raw RF data
