DSO9254A Acquisition Mode High Resolution

I would like to know more about the Acquisition mode of the 9254A Scope. I was not able to find much documentation online to help describe what each option in the Acquisition mode menu does and what is used for.

Particularly, I am interested in the High resolution option. It gives me what I am looking for, but I am not sure how it works.

Also I had a question/concern.

When taking the average of the incoming signal, in the Acquisition Mode menu, what does it take such a long time for the average to reach the value I have set it to.
Example: Average set to 1024 over a 20ns range, with signal freq = 76mHz at -5dBm

Should the time t = 104*20ns but it takes way too long.
Is it averaging over a larger signal window that is being seen on the scope?
How can we make it so the scope finds the average at a much faster time than it currently does?
