Would this line also induce some behavior?
Like a pass/fail message?
Or just a line?

==================================================
Eric, Just a line that you can set the value for and turn on and off.? Primarily used for quick visual indication of of how a measured signal compares against a set reference line.? I believe the line is usually labeled "ref" or "ref line" when it is displayed.? "limit line" might be another choice for a label to prevent confusion with reference level.

Some advanced analyzers do provide some type of pass/no pass or go/no go indication when the line is exceeded, but that seems a waste of memory space on the tinySA and might be better implemented in the software application if there was a user demand.

Clear, for the todo list if I have a spare moment....

Minimum RBW is 2.7kHz

Perfect, thanks.?

RBW means Resolution Bandwidth,e.g. the bandwidth of the narrowest filter before the power detector
This implies you can not see anything inside a good SSB transmission but you are able to see if there is a lot of over modulation
