(HP 8562A) Preselector Offset/Slope, Flatness filter diagram or visual?

[Kal_Ebration]

I have been calibrating SA's for over a year now by following the guide but I'm curious to know what the filters look like and how they are responding to values.  I tried searching for a bit and maybe I'm just not using the right terminology to find said visuals.

Any help or pointing in the right direction is much appreciated!

Thanks!
