摘要
基于当今社会对实验实践环节的重视与传统仪器仪表功能相对单一且价格居高不下的矛盾日益明显的现状,一种可以解决上述问题的全新实验仪器的诞生成为一个不可阻挡的历史潮流。鉴于上述情况,美国NI公司率先发起了对虚拟仪器的研究开发,由此带来了传统仪器向数字化、模块化以及网络化发展的变革。本文在对虚拟仪器的基本结构及信号处理的相关知识进行阐述的基础之上,采用图形化编程软件LABVIEW进行虚拟示波器的开发,从而实现了传统示波器向虚拟示波器的转换。使用这种方法可以将广大使用者从传统实验中解放出来,进一步实现实验的虚拟化。
Based on the situation that people pay more and more attention to the experiment,but the function of the traditional instruments is relatively single, and the prices are high , a new experimental instrument can solve the above problem has become an irresistible historical trend .In such circumstances, the NI company started the research and development of virtual instrument, And bring traditional instruments toward digital, modular and network. Based on the mastery of the basic structure of virtual instrument and the knowledge of signal processing,this paper use LABVIEW ,a graphical programming software ,to realize the development of virtual oscilloscope and achieve the transformation of the traditional oscilloscope to virtual oscilloscope .In this method, the majority of users will liberate from the traditional experiment, and virtual experiment will be realized.
