摘　　要：以单片机C8051f020作为主控制器,现场可编程门阵列(FPGA)作为主要的高速存储器,闪电型芯片ad9054为高速模数转换器,设计并实现了应用于采集均匀传输线回波信号的高速数据采集系统.通过实验,很清晰的观测到了传输线上行波的反射和延时现象.A high-speed data acquisition system based on FPGA for acquiring echoing signals of uniform transmission lines is designed and implemented with C8051f020 as the main controller, FPGA as the high speed memorizer, and FLASH chip of ad9054 as high-speed ADC. Through experiment, the phenomena of time delay and reflection of traveling wave process is observed.
