LTE MIMO上的MXA RSRX怎么测量

嗨,我是论坛的新用户,我正在使用MXA LTE-FDD调制分析对LTE的RS信号进行空中测量(用于电磁人的曝光目的)。
在表格错误向量摘要中,我看到RSTX和RSRX功率,假设在发射器处的LTE 2X2 Mimo信号和单个接收器(在我的情况下是天线+电缆)如何修改此参数的MIMO?
否则,RSRX功率是两个MIMO信号的RMS和。
关于它的另一个问题。
在MXA的同步菜单中设置2个TX天线,并为MIMO提供参考天线,与每个MIMO信号的接收器相比,RS功率是什么?
每个RSRX?

  Hi,  

I'm a new user of the forum, i'm using MXA LTE-FDD Modulation Analysis doing on Air measurements of the RS signal of LTE (for electromagnetic human's exposure purpose). In the table Error vector summary i see RSTX and RSRX power, supposing an LTE 2X2 Mimo signal at the trasmitter and a single receiver (in my case antenna+cable) how MIMO modify this parameter? Otherwise, is the RSRX power the RMS Sum of the two MIMO Signals.
Another question about it. Setting 2 TX antenna in the Sync menu of MXA and alternate the reference antenna for the MIMO what's is the RS power than I have at the receiver for each MIMO signals? RSRX for each one?

嗨Dave,我们正在使用具有UMTS和LTE个性的N9020A SA(89601A-B7U W-CDMA / HSPA调制分析,89601B-BHD LTE FDD调制分析)。
我们需要在文件中记录并导出在被测基站附近的空中测量的CPICH或RSRX电平的时间历史。
你能帮助我们吗?
提前问候

  Hi Dave,
we are using the N9020A SA with UMTS and LTE personalities (89601A-B7U W-CDMA/HSPA Modulation Analysis, 89601B-BHD LTE FDD modulation analysis). We need to record and export in a file the time history of the CPICH or RSRX levels measured on air in the nearby of the base station under test.
Can you help us?

Thank you in advance
