N5106A PXB如何求和两个衰落信道的输出？

问题1：在我的PXB中，选项612,634，JFP和QPF与N5106A-031（QTY = 2）并使用Fade（ext in）配置和FW 2.2.1.3。
如何求和两个衰落信道的输出？
我在模拟器中看到使用配置“1 Channel + Summed Interferer”或单用户MIMO（ext in）2x2,2x4等的部分方式，但这些需要非常昂贵的升级？
我想使用FPGA卡上的N5102A接口在外部创建和注入干扰源，而不使用PXB内部AWG或-EFP升级选项。
附图显示了我想要的内容。
是否有其他配置允许使用外部输入进行衰落和数字求和？
问题2：该网站将选项N5106A-FFP显示为“已停止”。
是德科技不再支持PXB产品中的信号捕获了吗？

  Question 1:

In my PXB with options 612, 634, JFP and QPF with N5106A-031 (QTY=2) and using the Fade (ext in) configuration and FW 2.2.1.3. How do I sum the outputs of  the two faded channels?

I see in the simulator there is a partial way using configuration "1 Channel + Summed Interferer" or Single-User MIMO (ext in) 2x2, 2x4, etc but these require very expensive upgrades? I want to create and inject the interference source externally using a N5102A interface from my FPGA card and not use the PXB internal AWG or -EFP upgrade option. The attached picture shows what I would like.

Is there another configuration that will allow fading and digitally summing using external inputs?

Question 2:

The website shows option N5106A-FFP as "Discontinued". Is Keysight not supporting signal capture in the PXB product anymore?
