摘要
文章基于ARM与CPLD技术设计了一种虚拟数字存储示波器。以S3C2410和EPM7128为控制器,采用高速A/D转换芯片AD9283设计数据采集卡。采用USB总线实现数据采集卡和PC机通信,基于Lab-VIEW开发虚拟示波器的控制面板及应用程序。该虚拟示波器具有数据采集、波形显示、频谱分析、数据存储与回放等功能。
Based on the ARM technology and CPLD, we designed a virtual digital storage oscilloscope. To S3C2410 and EPM7128 for the controller, using high-speed ND converter chip AD9283 to design data acquisition card. USB bus used for communications between data acquisltion card and PC, and develop virtual oscilloscope control panel and applications based on the LabVIEW. The virtual oscilloscope has many functions, such as data acquisition, waveform display, spectrum analysis, data storage and playback.
