250MSps dual channel high-speed data distributed acoustic sensing (DAS) acquisition card

PCIe-6920 is a PCIe x8 Lane, dual channel, 14bit resolution high-speed data acquisition card with a sampling rate of 250MSps. Onboard high-performance FPGA chip with abundant multiplier and RAM resources. By adopting high-capacity data caching and high-speed data transmission engine technology, real-time upload of raw data is supported, with a data transmission rate of up to 2GB/s. The driver program has good compatibility and supports multiple versions of 32/64 bits DAS (Distributed Acoustic Sensing) and DVS (Distributed Vibration Sensing) for WIN7, WIN8, and WIN10, which are relatively new technology directions in recent years. Compared with DTS (Distributed Temperature Sensing) technology, the requirements for devices are also increasing. Among them, the AD requirements in the system are very high, and it needs to have high sampling rate and high accuracy. Due to the long-term operation, the stability requirements are also very high. At present, our company can provide high-speed A/D (sampling rate up to 1GS/s 16bit) for DAS and DVS systems
