GY-DAQ-2510D 1GSps Dual-Channel 14-bit High-Speed DAQ Card for DAS & LiDAR

 Overview

The GY-DAQ-2510D is a DAS/LiDAR dedicated high-precision data acquisition card designed for high-end coherent demodulation scenarios, equipped with on-board high-performance Kintex UltraScale (KU060) 20nm process FPGA and large-capacity data cache. Adopting high-speed data transmission engine technology, it realizes 4GB/s ultra-fast real-time data upload via PCIe3.0 X8 interface, meeting the large-volume, high-speed data collection needs of 100km+ long-distance DAS fiber optic sensing systems.

With dual-channel 14-bit high-speed ADC, the card achieves 1GSps synchronous trigger sampling and 66dBc SFDR, ensuring high signal-to-noise ratio and low distortion for weak coherent signals. Its built-in phase demodulation algorithm module realizes coherent fading suppression and global full-fiber demodulation — a key advantage over traditional IQ demodulation DAQ cards, greatly improving the accuracy and stability of demodulated signals and laying a solid foundation for subsequent signal processing and event identification.

The card features good driver compatibility, supporting multiple versions of Windows and Linux systems, and programmable in C/C++/Python/Matlab. It avoids complex phase unwrapping operations for users, reduces the host CPU computing power requirements, and greatly lowers the development difficulty of DAS/LiDAR systems, realizing simple and efficient data reading and phase vibration analysis.
