摘要
采样示波卡的研制，采用了虚拟仪器的设计思想。该卡性能的设计指标为：最高采样率每通道３０Ｍｂ／ｓ；分辨率８位Ａ／Ｄ；通道数２；输入信号０—２０．０Ｖ；存储深度每通道６４ＫＢ。硬件包括Ａ／Ｄ转换器，高速缓存，采样时钟控制电路，地址产生器电路及与微机的通讯电路等。软件由采样控制模块，数据处理模块及人机界面模块等组成。经在ＰＣ２８６以上微机上运行测试表明：该卡达到了设计指标。
The sampling oscilloscope ,using the design procedure of virtual instrument,is developed.The specifications of the oscilloscope are as follows:a maximum sample rate of 30 mega samples per second per channel,8 bit A/D resolution,2 channels,0—20 0 V inputs,memory depth of 64 kilo samples per channel.The hardware consists of A/D converter,high speed buffer storage,sampling clock control and address generating circuits,and communication circuit connected with microcomputer.The software consists of sampling control module,data processing module,user interface module and so on.The operation and test on PC shows that the design specifications of sampling oscilloscope are reached.
