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。-The digital oscilloscope and a single-chip FPGA as the core, the choice of the sampling methods and the equivalent sampling technique designed to achieve a focus, so that not only works with real-time sampling, and the random sampling technique to achieve the equivalent of using real-time sampling rate the ADC for the 1MHz maximum equivalent 200MHz sampling.
