摘要
文中主要论述AD9850工作原理及利用该芯片实现的高频信号源系统。为了得到更宽频率范围的频率输出,本系统采用了先进的DDS+PLL技术。该高频信号源可实现FM调制方式,幅值和频率均可调,频率范围为10kHz～100MHz。
The basic principle of AD9850 and a high signal source system based on AD9850 are decribled. For more wide frequency , DDS + PLL is used in this system. The high frequency signal source can realize FM modulation and it's amplitude and frequency can be regulated digitally. The frequency range of signal source is between 10kHz and 100MHz.
