我们需要从300MHz以200MHz的步长跳频至6GHz，在跳频的过程中出现
“######## Error Code = 471, comment:[TALISE_setFhmHop : nextFhmRfPllFrequency is out of scan range”
或者
“######## Error Code = 467, comment:[TALISE_setFhmMode : Out of range fhmInitFreq requested”
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：
