complex 1x模式下采样率最高6.25Msps，采样率设置10Msps会报错
而complex 2x模式下采样率最高12.5Msps
我想问的是，这两种模式的采样数据有什么区别？为什么2x模式采样率能高一倍？希望能详细解答下。
complex 1x比complex 2x使用更小的采样率，采集的数据都为有效数据。

请问有效数据是什么意思？
能不能理解为complex 1x的采样率已经够用了，用complex 2x的更高采样率不太必要？
是的，一般complex 1x够用了，两者有效数据的区别，请参考下面的帖子说明。 https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/719503/awr1642boost-complex-1x-and-complex-2x-modes
