大家好,如何使用MXA N9020A测量BTS测量的相对代码域误差?
在BTS模式的Mod Accuracy选项卡中禁用它(可能与BTS / DL模式中的事实有关,DPDCH和DPCCH是时间复用的,而在MS / UL模式下它是I / Q分离)。
我正在考虑使用25.141附录E中的公式计算RCDE。报告的典型值约为-8.9dB,其中极限为-20。
请告知我的理解是否正确以及任何改进的测量方法。
任何相关文件的任何链接也会有所帮助。
非常感谢。

Hi all,
How can you measure Rela
tive Code Domain Error for BTS measurements using MXA N9020A?
It is disabled in the Mod Accuracy tab for BTS mode (perhaps to do with the fact in BTS/DL mode the DPDCH and DPCCH are time-multiplexed while in MS/UL mode it is I/Q separation).
I am thinking of calculating the RCDE using the equation from 25.141 Appendix E.
Typical values being reported is around -8.9dB where the limit is -20.
Please advise if my understanding is correct or not and any improved measurement method. Any links for any related documents will also be helpful.
Many Thanks.
