使用4片级联的2243芯片+TDA2采集数据，波形配置和数据采集过程中都没有报错，但最后Post时出现方波，导致RD图异常，且只有device3每帧的最后十几个chirp存在这种情况，device1、device2与device4都是正常的正弦波，请问这是什么问题造成的呢，应该如何解决？

你好，
Studio里带的mimo LUA配置也有同样的问题么？如果没有，请提供能复现问题的配置。
您好，感谢回复，这种情况不是每次测试都会出现，有时候就是正常的波形，出现这种错误时经常发生在这组数据的第一帧，以及其他帧的最后几个chirp，以下为波形配置脚本，您看一下有没有什么问题

你好，
如果是第一帧，这是一个已知的问题，建议不要使用第一帧数据。
