Product Overview

The DAQ-M250 Data Acquisition Card is a multi-channel signal acquisition and transmission board based on the PCIe bus architecture. It supports 4-channel synchronous ADC acquisition and 2-channel DA transmission, with a sampling rate of 250 MSPS and 16-bit quantization. The card is compatible with PCIe 3.0 x8. Its core processing chip utilizes Xilinx's high-performance Kintex UltraScale series FPGA, and it is equipped with one set of 64-bit DDR4 SDRAM onboard. Featuring rich interfaces and computing resources, the board includes synchronous trigger input and output interfaces, as well as a 10 MHz reference clock input, supporting multi-channel synchronous and co-source data acquisition and transmission.
