Embodiment Construction

[0027] A general-purpose oscilloscope relies on high input impedance to display and measure signal waveforms. As the name implies, it is not only suitable for observing a certain type of electronic signal, but can observe and measure in a certain way from DC to AC with a certain large voltage amplitude. and a device for analog signals. In order to achieve these goals, the oscilloscopes currently on the market are complex in design and comprehensive in design, and in terms of structure, they generally use some mechanical and electronic control and adjustment components, which are relatively large in size, and have problems such as power consumption and interference. It is difficult to popularize test tools that are cost-effective, convenient and practical, and small and handy. Therefore, the present invention changes the design idea of ​​the traditional oscilloscope, realizes the low power consumption design of the general oscilloscope, and innovates a circuit function that can...
