In the process of oscilloscope upgrade and iteration, the traditional analog oscilloscope is difficult to meet the needs of modern electronic measurement, compared with the analog oscilloscope, the digital oscilloscope has the advantages of higher measurement accuracy and stable display. As technology evolves, the performance and functionality of oscilloscopes continue to improve. Modern oscilloscopes use technologies such as high-speed ADCs and FPGAs to feature high bandwidth, high sampling rates, and deep memory depths. In addition, the digital oscilloscope also supports a variety of triggering methods and signal analysis functions, such as FFT transformation, spectrum analysis, and other functions.

Learning to design and produce a digital oscilloscope is very helpful for the cultivation of personal comprehensive ability, the digital oscilloscope project includes the design and development of single-chip microcomputer circuits, the calculation of signal conditioning circuits, the design of human-computer interaction and the design of shell models, etc., integrating analog circuits, single-chip microcomputer design, circuit and PCB design, shell design and other comprehensive knowledge. Combined with the beginner's acceptance of knowledge, this entry-level digital oscilloscope project is specially designed for this purpose, which is suitable for introductory training of electronics and introductory learning of single-chip microcomputer, and the project has the following characteristics:

• The design concept of core board and expansion board is adopted, and the plug-in device design is adopted to make learning easier;
• The core board is controlled by domestic GD32, which is compatible with other development boards of the same type.
• The project has a high degree of comprehensiveness and strong practicability, and can be used as a desktop daily instrument after the design is completed;
• The program has a wealth of learning materials, including circuit design teaching, PCB design, and code programming.
