DAS Acquisition Card (GY-DAQ-2480-E) Product Overview

Product Overview

GY-DAQ-2480-E/OE is a DAS full demodulation acquisition card based on network interface launched , with dual-channel 250MSps synchronous trigger sampling. As a network interface DAS high-speed data acquisition card, it uses Gigabit Ethernet or 10G optical port to communicate with the host computer. By adopting large-capacity data buffer and high-speed data transmission engine technology, it supports real-time upload of original data and demodulated data. The data transmission rate can reach 1000Mb/s, and the sampling optical port transmission can reach 10Gb/s. The acquisition card adopts dual-channel 14-bit high-speed ADC with sampling rate of 250MSps and supports DAS data acquisition of more than 100km. Built-in phase demodulation algorithm, can directly upload amplitude phase demodulation data, phase data can be directly used by users as vibration signals, without demodulation processing again, to achieve full cable demodulation; or upload the original sampling data for users to demodulate.

Compared with the traditional IQ demodulation acquisition card, the acquisition card has a built-in phase demodulation algorithm module, which realizes coherent fading suppression and global demodulation, greatly improves the accuracy and stability of demodulated signals, and lays a foundation for subsequent signal processing and identification. It avoids the user still need to unwrap the operation after getting the data, reduces the system's requirements for CPU computing power, and also greatly reduces the user's development difficulty, realizing the simple operation of data reading and phase vibration.
