| 摘 要： | 介绍一种自行开发的基于LabVIEW虚拟函数信号发生器。与传统函数信号发生器相比,该仪器不但界面友好,而且功能强大、操作简便。它不但可以产生正弦波、三角波、方波、锯齿波,而且还可以产生白噪声及多频波。输出波形频率范围更宽,具有相关参数的调整与同步显示及其幅度频谱分析功能。实现对输出信号的高速离散采样数据的本地存储,以便本地调用和远程传输。

| Abstract: | A new kind of virtual function signal generator based on the graph programming language LabVIEW is introduced,which is developed by us.It can not only generate some common signals,such as sine wave,triangle wave,square wave and saw-tooth wave and so on,but also do arbitrary function waveform and white noise signal.Comparing the conventional signal generator,it has some advantages such as the interface to be more friendly,more widely output frequency band,parameter adjusted more conveniently,realized more easily,high reliability and so on.It can display the output signal waveform and frequency spectrum.The sample data in high speed for output signals will be stored in the local computer.It is easy for local use or remote transmit. |
