为了解决这个问题,就需要用到Fast Lock功能。简单点说就是提前校准好每个频点的参数保存起来,下次要用的时候直接调用。这种方法将切换频率后的锁定的时间缩短到6us左右。 前面提到保存校准结果以及调用结果,需要一个媒介,这个媒介叫profile,可以将其理解为一组寄存器,读写这个寄存器组就能实现频率切换。AD9361包含8个...
ad9361fastlock模式下快速校准VCO。在FDD模式下校准完后TX发射出的频点偏移了一点。最多偏移了7M。流程是先通过FDD模式用常规校准完成后,TX的发射出来的频点并没有偏移,此时 AD9364/Ad9361的FastLock模式的使用 在FastLock下,对于配置文件profile的构建,最后两个config Word是通过读取寄存器得到吗,,最后两个config Wo...
常规模式下,可以检测247[D1]进行检测,但使用fastlock模式,调用profile实现调频,我检测247[D1]始终为1,所以请问在fastlock模式下,我该如何判定信号已经稳定?谢谢@ 色色隐隐 2018-08-22 10:24:42 AD9361 2 X 2 RF捷变收发器 电子发烧友网为你提供ADI(ti)AD9361相关产品参数、数据手册,更有AD9361的引脚图...
