This digital oscilloscope takes a MCU and FPGA as the core. We made emphases on the choice of the sampling methods and the implement of equivalent sampling as a result, our design not only has the real-time sampling mode but also can reach the highes

本数字示波器以单片机和FPGA为核心，对采样方式的选择和等效采样技术的实现进行了重点设计，使作品不仅具有实时采样方式，而且采用随机等效采样技术实现了利用实时采样速率为1MHz的ADC进行最大200MHz的等效采样。同时系统还具有可测2mV小信号、波形存储回放、测频、触发沿选择、校准信号输出等功能。-The digital oscilloscope and a single-chip FPGA as the core, the choice of the sampling methods and
