250MSps dual-channel high-speed data DAS acquisition card

The PCIe-6920 is a high-speed data acquisition card with a PCIe x8 Lane interface, dual channels, and a 14-bit resolution at a sampling rate of 250MSps. It features an onboard high-performance FPGA chip with abundant multipliers and RAM resources. Using large-capacity data buffering and high-speed data transfer engine technology, it supports real-time uploading of raw data, with a data transfer rate of up to 2GB/s. The driver software is highly compatible and supports multiple versions of WIN7, WIN8, and WIN10 (32/64-bit). DAS (Distributed Acoustic Sensing) and DVS (Distributed Vibration Sensing) are relatively new technological directions in recent years. Compared to DTS (Distributed Temperature Sensing), they require higher technical standards and more advanced devices. In particular, the system's ADC requirements are demanding, needing high sampling rates and high precision, as well as long-term stability. Currently, our company provides high-speed A/D converters (sampling rates up to 1 GS/s, 16-bit) for DAS and DVS systems.
