| 摘 要： | 对高速数据采集系统进行了研究,基于其采集速率的问题,提出了一种基于FPGA的高速数据采集系统。利用FPGA实现对12bit的A/D转换器ADC12D800的控制,使用其1.6Gsps双沿采样工作模式完成对400MHz以下高频信号的数据采集。通过设计数据存储方式来降低数据传输速率,使数据经USB传至PC机来实现高频信号地实时采集与存储。实验结果表明它可以实时、高效地完成数据采集,可以应用到雷达、通信、电子对抗等领域。

| Abstract: | Studied for the high speed data acquisition system, based on the acquisition rate this thesis introduces a high-speed data collecting system based on FPGA, which uses FPGA to control A/D converter ADC12D800 of 12 bit, uses dual-edge sample made of 1.6Gsps to complete the acquisition of high-frequency of 400MHZ , reduces data rate by designing the way of data storage and is transmitted via USB to a PC to realize the real-time data collection and storage for high-frequency signals. Results of experiments show that it can be applied to data-collecting in real-time and efficiently, and can be applied to the fields of radar, communication, electronic warfare and so on. |
