摘要
以89C52单片机为核心,设计并实现了一个低成本的数字示波器。系统由宽带电压跟随器、放大倍数调整模块、测频模块、采样保持模块、AD转换模块、数据存储模块、波形显示等功能模块组成,根据要求,对采样保持、水平扫描速度和垂直灵敏度的自动设置功能及波形参数测量功能等关键模块进行了重点优化。
Takes 89C52 MCU as the core, designs and realizes a low cost digital oscilloscope. The system consists of broad band voltage follower, magnification adjustor, frequency measurer, sampler, A/D converter, and data storage module, waveform displayer etc. According to the basic requirements, some important modules（such as the sampler, scanning speed and vertical sensitivity auto settings function, automatic measurement of waveform parameters etc.） are optimized in the design.
