摘要
介绍了一种基于单点稳态正弦激励法求系统频率响应曲线的频率响应分析仪的硬件、软件以及各主要功能模块的实现方法。这是一种利用集成和基于计算机的思想开发的准虚拟仪器系统，它把实现功能所需的主要模块，如Ａ／Ｄ转换器、信号发生器、跟踪滤波器等集成到一块电路板上，具有自动化程度高、功能齐全和性价比高的特点。
A PC based Frequency Response Analyzer is introduced in the paper.The hardware and software of the analyzer are described.Its features are (1) main functional modules,such as A/D,signal generator and track filter,are integrated in a printed circuit board,(2) It is a pseudo virtual instrument with multi function,high automation and low price.
