2-channel DTS dedicated high-speed data acquisition card (for Phase OTDR phase optical time domain reflectometer system)

Phase optical time-domain reflectometry (Phase-OTDR) system Low-cost phase optical time-domain reflectometry (Phase OTDR) system DTS dedicated high-speed data acquisition card is a high-speed weak signal data acquisition card. DTS dedicated high-speed data acquisition card adopts the hardware real-time accumulation and averaging technology designed by our company's technological innovation to realize weak signal enhanced acquisition and extract relevant signals submerged by noise. Through on-board synchronization technology, the original signal can be accumulated up to 32768 times, which can increase the signal-to-noise ratio by 180 times. It is a widely used weak signal detection board. DTS dedicated high-speed data acquisition card has two 12-bit high-speed A/D converters on board. According to customer needs, two sampling rate versions of 100MSPS and 125MSPS can be provided. DTS dedicated high-speed data acquisition card has carefully designed a unique parallel synchronous signal acquisition and accumulation technology, so that acquisition and accumulation are completed synchronously. The computer takes only 3 seconds to get the final result after 16,000 acquisitions and accumulations of the original signal with a length of 10,000 points. The DTS dedicated high-speed data acquisition card has two trigger modes: external trigger and internal trigger. Customers can choose the device trigger acquisition card mode or the acquisition card trigger device mode. After careful signal integrity processing, the trigger pulse overshoot given by the device is within 5%, and the superior signal quality ensures that the device is not triggered by mistake. The DTS dedicated high-speed data acquisition card can accurately recover, detect and measure weak signals submerged by noise background, and is particularly suitable for distributed fiber optic sensing systems.

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
