一种示波器扫描电路设计

Design of an Oscilloscope Scanning Circuit

电信号是不可见的,可是对信号进行可视化的观察对科学研究很重要,所以研究示波器的扫描电路是非常有必要的。以电压发生器为研究主体,并在此基础上,采用的是发生环扫描的方式来生成扫描锯齿波电压。其触发方式有三种可以供选择,分别是:常态、自动和锁定,最后对电路装配以及装配后的调试,产生故障检修的方法进行了必要的说明。

The electrical signal is invisible,but the observation of the signal is important for scientific research,so it is necessary to study the scanning circuit of the oscilloscope.Taking the voltage generator as the research subject,and based on this,the ring scan method is used to generate the scanning sawtooth voltage.There are three trigger modes to choose from:Normal state,automatic and lock,and finally the necessary explanation for the circuit assembly and post-assembly debugging,and the troubleshooting method.
