Description: 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 highest equivalent sample rate of 200 MHz using the real-time sample rate of 1 MHz, by way of random equivalent sampling. At the same time, this system has many other functions, such as 2 mV small-signal measuring, storage and re-display of waveform, measuring frequency, selective trigger edge, output of the correction signal and so on.-This digital oscilloscope takes a MCU and FPGA as the core.

Description: 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 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. At the same time, the system also has a small signal can be measured 2mV, waveform playback memory, frequency measurement, the trigger along the choice of the calibration signal output functions.
