adrv9009在跳频应用中，中间频点出现“######## Error Code = 471, comment:[TALISE_setFhmHop : nextFhmRfPllFrequency is out of scan range”错误

Question

我们需要从300MHz以200MHz的步长跳频至6GHz，在跳频的过程中出现 
 &ldquo;######## Error Code = 471, comment:[TALISE_setFhmHop : nextFhmRfPllFrequency is out of scan range&rdquo; 
 或者 
 &ldquo;######## Error Code = 467, comment:[TALISE_setFhmMode : Out of range fhmInitFreq requested&rdquo; 
 的错误。 
 
 请问出现这个问题的原因可能是什么？

您必须使用以下结构来设置跳频模式的频率范围： 
 
 设置范围后，调用如下 API 函数设置跳频频率。为确保在设置每个跳频频率之后，RF PLL 有足够的时间稳定到新的频率上（即PLL正常锁定），建议每次跳转后添加延迟（2~5s）： 
 
 你可以参考随附的 IronPython：
