资料介绍

为了满足有源滤波电路等模拟电子电路频率响应测量的需要,克服传统测试方法中仪器比较多,步骤较复杂且容易产生较大误差的缺陷,介绍了一种基于LabVIEW的虚拟扫频仪设计方法。简述了该扫频仪的整体设计方案和测量原理,详述了扫频仪主要的软件设计模块。实验结果表明,该扫频仪能直观测试电路的频率特性及绘制出相应的幅频特性和相频特性曲线,能较好的满足有源滤波电路频率响应的测量。

In order to satisfy needs of frequency response measurement of the analog electronic circuits such as the active filter circuit,and overcome defects of the traditional testing method such as equipment is more,steps are too complicated and prone to a larger error,a design method of virtual frequency sweeper based on LabVIEW is introduced in this overall design scheme and measurement principle of the frequency sweeper are described briefly,main software modules of the frequency sweeper are described in detail. The experimental results show that the frequency characteristic of the frequency sweeper can direct test circuit and draw the corresponding amplitude-frequency characteristic and phase frequency characteristic curves. The virtual frequency sw...
