Someone with a Lecroy 12 bit scope (HDO*** ? ) can please tell me how the noise reduction with the enhanced resolution works on practice? ie does one need to setup another math channel with the enhanced res on it, or does it apply directly to the channel being mesasured like the High-res in Tek scopes?
We got a HDO6034A at work, you can do enhanced resolution via math, but also directly in the channel menu.
Can make a pic from it tomorrow.

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...

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.
With eres, the signal is clear.
With eres, the signal is clear.The "same" +3 bits of enhancement produced different results and frequency cutoff ? Even when the timebase/samplerate seems to be the same?
ERes is quite well documented actually... See attachment..
That is a sleazy comercial, not something I would expect from a great company..
(i don't like comparisons from LeCroy or Tek either, they all go too far in this kind of material)
Comparing 1 GHz/2.5 GS/s with a 8 GHz 40GS/s and noting the lather one is more accurate near 1 GHz...
Yes, you are correct, my comparison is with the Keysight Infiniivision Series 3000X, 4000X, and 6000X, which I use every day in my work. And for some reasons they are just perfect for my applications.
I don't have a S-Series nor have I used a Keysight S-Series scope. (Maybe one day!) The video compares two scopes in the same price range and the LeCroy does show some basic limitations. I also think they set the S-Series to 1 GHz bandwidth. One could probably also find limitations in Keysight scopes, no question!
My personal experience with LeCroy scopes have just been terrible. And yes, I know that LeCroy makes some amazing high end scopes for research but they are in a range of not affordable to normal businesses.
LeCroy is niche, or not. They are great for R&D, science folks, test... They are "scopes with analysis lab built in". If you need that, they are first choice, if you don't, than you don't...
I find them logical to setup, but I never was a button twiddler, more of a make plan first before doing something...
We are all different and have different needs..
