摘　　要：逻辑分析仪是一种用于分析数字系统逻辑关系的仪器。一般情况下数字电路有多路信号,而使用普通的示波器测试时,最大范围只能同时进行两路波形信号的测试,这显然不能够满足使用者的需求。针对此类问题,基于51单片机设计了简易逻辑分析仪,其特点是价格低廉,功能多样,易于上手,可满足大部分用户的需求,且经调试运行良好,有一定的应用前景。Logic analyzer is an instrument used to analyze the logic relationship of digital systems.Usually,digital circuits have multiple signals,and it can be only tested two signal waveforms at the same time when thde ordinary oscilloscopes is used to test and analyze them,which obviously cannot meet the needs of users.In view of this kind of problem,the paper designs a simple logic analyzer based on 51 single chip microcomputer.It has the characteristics of low price,multi-function and convenient use.It can meet the needs of most users,and has a certain application prospect after debugging.
