【摘要】 介绍一种自行开发的基于LabVIEW环境的VI-1型虚拟测试系统。与传统测试系统相比,该仪器不但界面友好,而且功能强大、操作简便。其突出特点体现为功能的高度集成,它集低频信号源、示波器、频谱分析仪于一身。它不但可以产生并显示正弦波、三角波、方波、锯齿波等低频测试信号,而且可以同步观测被测点的时域响应并进行频域分析。更多还原

【Abstract】 A new kind of VI-1 virtual measurement system based on the graph programming language LabVIEW is introduced,which is developed by us.Comparing the conventional instrument,it has some advantages such as the interface to be friendly,parameter adjusted more conveniently,realized more easily,high reliability and so on.The characteristic is its high integrated in functions. It gathers low frequency generator,oscilloscope and spectrum analyzer together.It can not only generate some common signals,such as sine wave,triangle wave,square wave and saw-tooth wave,but also can analyze and display the measurement signal waveform and frequency spectrum.更多还原
