Hi Erik

My humble opinion is leave it as is. It is working very well with the AGC functions and serves the first time user best possible as he hardly need to know what he is doing ?

I have both HP SA with coupled att and ref level where you can uncouple and also change the coupling ratio. I have also R6S SA where everything is fully manual so whatever used is a matter of seeing the impact of the various settings, there is no “automatic optimum” and sometimes it the dynamic range which has to be optimized, other times the linearity

Kind regards

Kurt

For a first time user, would it be better to have coupled (e.g starting attenuation level) equal to refelevel if reflevel >= 0?
Or should it be better to go to coupled mode if the reflevel is manually set to >=0?
Or leave like it is now?
