摘要
介绍了一种基于PCI总线的数据接入设备,通过采用专用的数据记录软件和高速数据存储接口,对综合基带解调后输出的1kbit^30Mbit/s串行数据进行帧搜索和打包,并通过PCI总线送入计算机,在计算机上进行数据记录。数据记录完毕后可进行误码率测试和事后数据浏览和回放。
This paper introduces a data connect equipment based on PCI bus, By using special data record software and high speed memory interface, the serial data（ from 1 kbps to 30 Mbps） which output from integrated baseband demodulation can be searched and packaged, then the data recording is implemented on computer after the serial data being input into PCI bus. After completing the recording, the BER measurement and the data revewing and replaying can be conducted.
