基于虚拟仪器平台的示波器设计

Oscilloscope Design Based on Virtual Instrument Platform

介绍了基于虚拟仪器平台的示波器的设计过程。底层硬件电路上采用现场可编程门阵列作为逻辑控制器件,上层使用LabVIEW软件进行PC机上应用软件的开发,通过USB总线实现通信。该示波器可以实现2通道波形的显示,读取波形幅值并存储波形。它在功能、易用性、精度上都达到了很好的效果。

Introduction was made to the design process of oscilloscope based on virtual instrument platform. The bottom hardware circuit adopted field programmable gate array as logic controller, the upper layer used LabVIEW software to develop application software on PC and communication was realized by USB. The oscilloscope could carry out two-channel display, reading waveforms＇ amplitude and storing them. It has good effects in functionality, manipulation and precision.
