摘要
简述了电子束偏转扫描原理和周期性波形设计方法,介绍了基于AT 89S51单片机的双通道数字扫描信号发生器的设计及其实现。利用串口通信,用户可以通过PC机选择所需信号波形。
This paper analyses the principle of the electron beam deflection and the method of generating the periodic waveform. It discusses the design of double channels digital scanning signal generator and the realization methods of software and hardware based on AT89S51 singlechip. Based on serial communication,the users can cboose the waveform by using PC.
