Here's a start. All from 28E comparing the Duo and Ultimo. Most noteable thing is the Ultimo tuner seems to become less sensitive above 12400MHz.

Thanks, do you also have the percentage values? I'd really like to have percentage values of the DUO compared to dB values of another device (as accurate as possible). With dB values only I have to make a correction on a correction function, if you know what I mean...

When in dB the percentages are possible they are relative to the maximum possible dBs

So we don't have the required data.
