摘要
针对传统示波器价格昂贵,设备更新周期长的现状,结合虚拟仪器技术性能高、开发周期短等优越性,以Lab-VIEW8.6软件为平台,以计算机和基于音频芯片的数据采集卡为硬件设计了双通道虚拟示波器。虚拟示波器实质上是集前端信号采集、信号调理与传输、后端信号处理于一体的测试系统,能够完成模拟信号的采集、波形显示测量、数据处理等,在低采样频率测试场合,可以代替传统示波器,操作方便、成本低,具有一定的实用性。
Due to the traditional oscilloscope is expensive and the equipment update cycle is long and the virtual instrument technology has superior performance,a data acquisition card was designed according to the audio chip with analog-digital conversion function.And a virtual oscilloscope was designed based on LabVIEW8.6 software platform.The virtual oscilloscope and data acquisition card constitutes a measurement system,which can be able to complete the analog signal acquisition,waveform measurement and data processing.In the low-frequency test cases,it can replace the traditional oscilloscope,and it is practical.
