基于NI ELVIS的电子实验设计 摘　要 随着低成本高性能的计算机资源普及运用，数字化仪器平台逐渐取代传统电子仪器已成为一种趋势。我国理工科学校的教学、科研需要大量的测量分析仪器设备，特别是电子类实验教学，每种仪器都必须配置多套，而且有些仪器设备价格十分昂贵。因此购置仪器设备的巨大投入经费，一般学校难以承受，造成仪器设备缺乏和过时陈旧等现象，严重影响教学科研效果。另外，由于传统电子学实验室教学模式存在的弊端，造成实验室设备利用率低，实验信息管理混乱，实验教师工作繁杂，最终不仅仅浪费了学校大量的人力物力，而且学生还不能真正地掌握实验，培养过关的动手能力（学校实验室仪器配备不全，一些必要的实验无法展开）。 如果把虚拟仪器运用到实验教学和科研中，不但可以节约大量仪器设备的经费投入，而且能够提高实验教学和科研的质量与效率。尤其是NI ELVIS在数字电路实验教学中的应用虚拟仪器Based on the NI ELVIS electronic experimental design Abstract With popularization using low-cost high-performance computer resources, digital instrument platform is gradually replacing traditional electronic instrument has become a trend. School teaching and scientific research in science and engineering in our country needs a lot of measurement analysis instruments, especially the electronic experimental teaching, each instrument must be configured more sets, and some equipment is very expensive. Therefore buy equipment investment funds, general school unbearable, causing the phenomenon such as lack of obsolete and outdated equipment, seriously affect the effect of teaching and research. In addition, due to the insufficiency of the traditional electronics laboratory teaching mode, lab equipment utilization rate is low, the experiment information management chaos, the experiment teachers work multifarious, in the end not just wasted a lot of school resources, and students cant really control experiment, train pass ability (school laboratory instrument equipped with is not complete, some necessary experiments can not open). If the virtual instrument is applied to the experiment teaching and scientific research, not only can save a lot of instruments and equipment of funds investment, but also can improve the quality and efficiency of experiment teaching and scientific research. Especially the virtual instrument in the digital circuit experiment teaching, the application of effect is more obvious.
