摘要
根据DDS基本理论,研究了以DDS技术为基础的用于数字式宽带频率特性测试仪中扫频信号源产生的设计方法,经过实验知此信号源性能良好。
According to the basic theory of Direct Digital Synthesis(DDS),we study a method to generate the sweep frequency signal for the digital broadband frequency-characteristics testing instrument based on DDS.With the experiments,the signals show the good properties.
