ENA E5080A如何测量IQ解调器IF相位/幅度差异？

我得到了ENA E5080A的演示，以确定我是否能够测量IF输出IQ解调器相位/幅度差。
我们在使用旧的8753E / D之前做到了....旧的8753的问题是它们显然不能永远存在:)我们正在寻找新的解决方案。
我说ENA是一个演示，因为它有大多数可用选项，包括频率偏移。
所以我的问题是：如果我使用SMC（混音器标量）选项我可以选择并输出接收，唯一的问题是我只能选择一个接收器（我需要两个）。
如果我在SMC通道中添加额外的跟踪，您仍然只能在该特定通道中使用一个接收器。
为了清楚起见，我需要使用外部生成器来实现我能够在SMC通道中配置和设置的LO。
看起来SMC选项无法在当前固件配置中测量IQ解调器。
另一种选择是在两条迹线之间使用具有数学函数的频率偏移。
我可以设置一个带有两个迹线的通道（S21和S31）并在外部设备配置菜单中设置外部LO发生器，但是我没有在频率偏移菜单中看到外部发生器。
看起来像频率偏移选项不能像SMC选项那样测量当前固件配置中的IO解调器。
有没有办法强制外部发生器出现在频率偏移菜单中？
有没有其他方法可以测量ENA E5080A上的IQ去调制器相位/幅度差异？
演示ENA E5080A的固件版本为A.11.00.04。
我知道我可以在PNA-X上进行测量，但是我们需要低成本解决方案来解决为什么我们要研究ENA E5080A。
问候。

  I got demo of ENA E5080A to determine if I will be able measure IF output IQ de-modulator phase/amplitude difference.
We did that before using old 8753E/D ....  The problem with the old 8753 is that they apparently can't live forever :)  
We looking for new solution.
I stated that the ENA is a demo as it have most of the available options, including frequency offset.
So what my problem:  
If I am using SMC (mixer scalar) option I can choose and output receive, the only problem I can choose only one receiver (I need two).
If I add additional trace with in SMC channel you still can only use one receiver with in that particular channel.  
To be clear I need to use external generator for the LO that I was able to configure and set in SMC channel.   
Look like SMC option will not work to measure IQ de-modulator in current firmware configuration.

Another option is to use Frequency Offset with math function between two traces. I can set one channel with two trace (S21 & S31) and set external LO generator in External Devices Configuration menu, however I do not see that external generator in Frequency Offset menu.
Look like Frequency Offset option will not work to measure IO de-modulator in current firmware configuration as in SMC option.

Is there any way to force the external generator to appear in frequency offset menu?

Is there any other approach to do measure IQ de-modulator phase/amplitude difference on ENA E5080A?

The demo ENA E5080A have firmware revision A.11.00.04.

I know that I can do that measurement on PNA-X, however we need low cost solution that why we are looking in to ENA E5080A.

Regards.
