AWR1443+DCA1000EVM：PostProc 作出的图明显异常

你好，

我在用AWR1443＋DCA1000EVM，并且通过TI官方的mmWave Studio获取了rawdata，但是PostProc作出的图与我的实验设置完全不一样，甚至可以说是异常。我之前也曾经询问过，也尝试过各种方法，但均没有用，下面是我mmWave Studio设置的详细图。

然后我也尝试了用test source enable，详情请见下图，也是没起到作用：

可以看出2D-FFT均是异常值，请告诉我接下来我该怎么做才能解决这个问题。

谢谢

你好，

附上成功采集数据的output打印信息供参考，另外，DCA1000板卡上的拨码开关如图所示，你可以对比一下打印信息及拨码开关有没有什么区别。

您好，

非常感您的回复。不过我按照步骤一步步来，还是没有改善，唯一的不同就是我的设备在LP ADC Mode情形下，只能用LOW POWER ADC，而用regular ADC时，连接不上：

除此之外，其他信息均与你提供的类似，请问我设备是否有问题？

谢谢

您好，

我在最近尝试无果后，我又尝试换了一个低版本mmwave studio来捕获rawdata，结果更加神奇了。PostProc出来的图起先看着跟原图差不多，但是过一段时间后，PosProc的图又回到了之前的状态。更为重要的是，我并不能通过此判定rawdata正确与否。详情见下图。

我在论坛里查询了关于如何判定rawdata的文档，并没有找到，请问是否有相关的用AWR1443+DCA1000EVM捕获数据并作图的视频，以便我判断rawdata正确与否。

谢谢

建议你把这种问题放到英文的E2E论坛：

回复 Wesley He:

您好，
我早已在英文论坛询问了，对方也不知道是什么状况。其实我一直有一个小小的建议，那就是如果您方便的话，您能不能也尝试用AWR1443 ES3.0和DCA1000EVM使用mmWave Stuido 2.0.2版本捕获 rawdata，然后把您的硬件配置，软件参数配置和output以图片形式发给我，我将感激不尽。
祝好！
