摘要数字存储示波器是随着数字电路的发展而发展起来的一种具有存储功能的新型示波器。原先人们看好的模拟示波器的一些优点，目前数字示波器已完全能够做到，特别是在捕获非重复信号、避免信号的虚化和闪烁、在时间上从触发事件反问寻迹——实现在电路中隔离故障等方面，数字示波器显示出了模拟示波器无可比拟的优势。因此，数字示波器由于其优势的性能、良好的性能价格化，刚一问世,就显示出它强大的生命力,各行各业均迫切需要,有其广阔的发展前途。本简易数字存储示波器,以单片机为控制核心,由通道调理、触发、波形显示等功能模块组成。本系统对触发系统、水平扫描速度和垂直灵敏度的自动设置功能（AUTOSET）及波形参数测量等功能进行了重点设计。设计中采用了模块化设计方法，并使用了多种EDA工具，提高了设计效率。整个设计实现了存储示波器的所有功能要求，达到较高的性能指标。关键词：存储器，转换器，数字存储示波器，单片机ABSTRACTIt is that one developed with development of the digital circuit is new-type oscillograph which stores the function that the figure stores the oscillograph . Original ancestors see some advantages of the good simulation oscillograph , the digital oscillograph can already be accomplished at present, catching and is not repeating the signal, avoiding melting and glimmers specially emptily, reply the mark of seeking from the incident of touching off on time of the signal --Realizing it in isolating the trouble in the circuit etc., the digital oscillograph demonstrates the incomparable advantage of the simulation oscillograph . So digital oscillograph because performance , good performance price of advantage their, just coming out , demonstrated its strong vitality, all trades and professions needed urgently , there is its wide development prospect. .This simple and easy figure stores the oscillograph, regard one-chip computer as the core of controlling, nursed ones health, touched off by the pass-way, the wave form shows, etc. the function module makes up . Such functions as automatic establishment function (AUTOSET ) and wave form parameter that this system scanned the speed and vertical sensitivity in touching off system , level are measured have been designed especially. Have adopt the module design method in the design, has used many kinds of EDA tools, have improved design efficiency. The whole of functions of designing and realizing storing the oscillograph require , reach the higher performance indexKeyword: the memory , the converter, the figure stores the oscillogra
