Build the best data acquisition platform powered by PhotoSound® Applications Photoacoustics (Optoacoustics) X-ray Induced Acoustics Thermoacoustics Acoustoelectrics 3D Tomography Photoacoustic Microscopy (PAM) 2D Imaging Multi-Sensor Monitoring Non-Destructive Testing Transducer Manufacturing Low Voltage Ultrasonics The LEGIONTM ADC unit offers fully parallel operation for simultaneous data acquisition from all channels without multiplexing in an ultra-compact external USB enclosure. Each unit supports 128- and 256-element detectors. Up to 16 ADC units can be operated in parallel to enable an unprecedented 4096 data acquisition channels. Incoming analog signals can be amplified on each channel by a fixed 40 dB using optional, integrated preamplifiers.

FEATURES Each LEGIONTM ADC undergoes a rigorous quality control process to ensure that all channels and features are operating at the highest level of performance. Thoroughly designed and meticulously planned, the LEGIONTM ADC supports a wide range of applications. Parallel Channels Connect up to 4 units in parallel and up to 16 units using our LEGION hub to acquire more data at fast data acquisition rates. Programmable Trigger Outputs Generate trigger output at defined rate or repetition of external trigger input with programmed delay. Output trigger supplied through electrically isolated...

Imaging and Data Acquisition Solutions Input Connectors The unit comes with two SAMTEC SEAFP series ports on each 128-channel bank. Each port can be fitted with preamplifiers and medical grade connectors that support thirdparty 128- and 256-element probes. Protective Housings Durable and light plastic enclosures with integrated cooling fans and aluminum panels that protect PCBs from unintended exposure. Programmable Gain Each analog channel has integrated amplifier with digitally controlled gain. Amplifiers integrated inside ADC chips are controlled using bundled software or a...

SOFTWARE The LEGIONTM ADC Standalone Software Package included with every unit is based on the MATLAB® computing environment and provides complete control over all unit functions. A free-of-charge backend SDK written in C++ is compatible with many frontend languages such as LabView, MATLAB®, etc. The Capture and Trigger Settings Window provides settings for trigger inputs/outputs, the internal signal generator parameters, and trigger output parameters. In the trigger selection table, one of five available inputs (two optical, two external electrical and the internal signal generator) are...

Imaging and Data Acquisition Solutions The Main Viewer Window displays the list of channels to show/hide on each device and the virtual oscilloscope. The default channel mapping can be reassigned to match the variety of ways in which third-party probes are connected. The Plot Control Window controls the channels selected for display as well as the scale of the plot in the main window. Additionally a sensors map can be assigned to view signals from specific elements. Configurations Manager Window allows for entering the various gain, attenuation, and filter settings. These settings include...

VERSATILE R1.2 Legion ADC - Max Data Transfer with Various Decimation Factors Effective Sam- Decimation # Samples Per Frame Acquisition Max Trigger Rate (Hz) Factor* Frame Time pling rate (µs) (MS/s) *Decimation Factor down samples the fixed 40 MSPS rate of the Legion ADC by the factor specified. This does not physically change the sampling rate of the Legion ADC but instead drops the sampling events in the memory buffer needed to reach the specified down sampled sampling rate. The dropped events are equally temporally spaced. Thus, the sampling rate of the output data transmitted to the PC...

Imaging and Data Acquisition Solutions OPTIONAL PREAMPS Optional 122 Channel preamplification boards add an additional 40 dB of fixed gain and change the input from low (50 Ω) to high (2.2 MΩ) impedance. Preamplifiers on each channel measure only 2 x 25mm, resulting in an overall compact design. The entire assembly (ADC+AMP) is integrated into a single, protective housing. Medical Grade Cannon QLC260 Compact, 260-pin connector for newer probes and ring-arrays. Each channel is connected to a signal and ground pin to minimize crosstalk. Cannon QLC260 connectors have superior shielding which...
