电子示波器是我们无线电电子学课程要讲的内容之一,也是无线电电子学实验中要经常用到的一种仪器。但是,仪器厂生产出来的电子示波器一般结构较复杂,学生在学习中困难较大,对其工作原理不易弄懂;对面板上各旋钮和开关的作用不易掌握。因此,自制一架课堂教学和实验室演示用的示波器示教板,对同学了解示波器的工作原理及培养同学使用示波器的技能技巧都有很大的帮助。电子示波器能够把眼睛看不见的电的现象变成看得见,它是利用高度聚焦的电子流撞击涂有发光体的萤光幕上来记录所研究的物理过程的设备,在结构上一般由:阴极射线示波
Electronic oscilloscope is one of the topics we talk about in the course of radio electronics, and it is also an instrument often used in the experiment of radio and electronics. However, the general structure of the electronic oscilloscopes produced by the instrument factory is complex. Students are more difficult to learn and can not easily understand the working principle of the electronic oscilloscope. The functions of the knobs and the switches on the panel are not easy to grasp. Therefore, a self-made classroom teaching and laboratory demonstration oscilloscope teaching board, to understand the working principle of the oscilloscope and students to use the skills of oscilloscope training have great help. An electronic oscilloscope capable of visualizing the invisible electrical phenomena of the eye is a device that uses a highly focused electron flow to impinge upon a fluorescent screen with a luminophore to record the physical process under investigation, Cathode ray oscilloscope
