DTS dedicated high-speed data acquisition card (for Phase-OTDR 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.
