基于FPGA的虚拟示波器设计

Dummy Oscilloscope Design Based on FPGA

介绍了一种基于FPGA的双通道60MHz的虚拟示波器设计。利用高速A/D转换器ADS5237实时采样输入信号,通过USB总线将实时数据送入PC,在PC上实现波形的实时采样、分析、存储和显示。同时给出了具体电路的实现方法,通过运行数据采集程序及处理程序,表明该系统工作稳定可靠。

This introduce a oscilloscope whit two chunnels base on FPGA which can collect data on a high speed as 60MHz. Collect real time data by a high speed A/D converter ADS5237 and transmit it to PC by the USB bus. It can sample, analysize, store and display the real time wave by PC. At the same tine, the associated circuit design is given. Through running the data acquisition and processing the program, knowing that this system work stable.
