在电子技术高度发展的今天,在生产、科研和教学各个领域中,作为电子测量仪器,示波器可以说是应用最广的一种。电子是肉眼看不见的,但借助示波器可以显示出电子变化运动轨迹。一台示波器的电路是比较复杂的,最简单的示波器也都包括:电源、示波管、扫描发生器、同步电路、水平和垂直偏转板及放大器等部分,而每一部分又是一个复杂电路。本文仅向初学者从使用角度介绍 In today’s highly developed electronic technology, in the production, research and teaching in all fields, as electronic measuring instruments, oscilloscope can be said to be the most widely used. The electrons are invisible to the naked eye, but the oscilloscope can show the trajectories of electron changes. An oscilloscope circuit is more complex, the simplest oscilloscopes also include: power supply, oscilloscope, scan generator, synchronization circuit, horizontal and vertical deflector and amplifier and other parts, and each part is a complex circuit.
