摘要
在跳频通信对抗系统测试中，往往需要有一可以按预置进行频率跳变的信号源。采用ＡＤ９８５０直接数字频率合成（ＤＤＳ）器集成电路可制作一个实用的跳频信号源。文中对ＡＤ９８５０的内部组成原理进行了深入浅出的说明。
A signal source which frequency hops in a prescribed manner is often needed in the test of the frequency hopping communication and counter measureing system.A practical frequency hopping signal source is made based on the AD9850 direct digital frequency synthesizer.The internal architecture of AD9850 is introduced and the components of the frequency hopping signal source system and its control are also analyzed.
