AD9361正常更改射频频率需要设置一些寄存器,然后开启VCO校准,等待锁定。这个过程时间是比较长的,大概在37us~508us之间。如果你的系统是一个跳频的TDD系统,那相当于每个时隙都要浪费这个时间等待VCO锁定,开销实在太大。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...
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...

For the fast AGC mode, there are other configuration bits and registers used to determine a low power condition. See the Gain Control User Guide for more information. Control Output 6 (CH1 Lg LMT Ovrg) This signal transitions high if a large LMT overload occurs (threshold set by 0x108)....
