Can make a pic from it tomorrow.

Yes please, take a pic of both ways and see if the noise reduction works and is the same.

Of course it works...
Question is: what are your expectations and criteria for it?
PartialDischarge:
I just want to see how it is activated and that it works, even just for the usec division which is not much for these scopes, I don’t have access to one of these. I have had already 2 customers who have these scopes but seem to have no idea on how to setup this mode or that it exists. There is serious lack of basic knowledge on how to measure with a scope in young engineers today, people measuring noise in pkpk instead of rms etc...

I agree there is widespread lack of detailed knowledge.. In part because scopes have never been more powerful (complicated).
And also by nobody reading manuals anymore apparently..
ERes is quite well documented actually... See attachment.. There are several white papers on LeCroy site that go into even more details.

If those scopes have some options, it is very likely that these include signal filtering. From my experience with Lecroy scopes these are even harder to setup but have the potential to create much steeper high pass, band pass and low pass filters which could be a better solution to isolate signals which live in a certain frequency band.
@2N3055: I'd don't think the Eres principle is the problem but the user interface. From what I have seen from my Lecroy Wavepro 7k is that it is very powerfull but getting math & functions going, is far from trivial. You really need to know what you are doing and what you are after.
If the goal is to have a scope that can do high resolution and simple averaging functions, then other brands which simply have 'high res' and average modes are far easier to drive.
Martin72:
Eres in the channelmenu..
Signal was stopped(because I had to give the DUT away... ;) ), you can see some small disturbances on it.
With eres, the signal is clear.
But you can also use eres as a mathfunction ( 8....EIGHT mathchannels..LOL).
