Huawei eNodeB FFT frequency scanning
I am trying to use the FFT freq. scan ("high resolution online freq. scan") on a TD-LTE Huawei eNodeB, but I cant find any documentation about how it works precisely.
For example it is clear that it only works, when the cells are in RX mode, but it is not clear if the cell's normal uplink traffic is also visible in it? For example if a normal user is uploading, will I see that uplink traffic in this FFT scan as well?
This is what I see:

It is not constantly there, but within 10-15 seconds it is relatively easy to catch.
If someone has an idea, or have some documentation about how FFT scan works on a Huawei eNodeB, that would be lovely.
MOD:
Found this link, but it is not helping about what it is measuring exactly:

MOD2:
Next week I will try to create some measurements on a test cell with no interference and a single UE to see the behavior. Non the less, if someone can shed some light on it, please don't hesitate to share.

Dear
If you have the log of FFT scan which tool will you use to analysi?

I think omstar or FMA can parse it

In FMA we have "LTERSSIAnaly_VXY" tool to decode trace results.
