+1dB touch button can't advance to more than -59.0dBm

[viulian]

Hello,

Running the latest available version for TinySA Ultra (1.4-165).

I noticed a problem related on the Signal Generator with AM Modulation. If you reach a level inferior to -59dBm and you keep pushing the +1dB touch button, once the level reaches -59dBm, the +1dB button does not increase the value anymore. The +10dB button still works.

Hard to describe in words, maybe a video explains better ?

It doesn't matter if you first turn the SigGen ON followed by setting the AM modulation, or you set AM mod first then turn on the SigGen. Sometimes it gets "stuck" at -58.5dBm.

More rarely, using the same buttons, I get a popup with "Output level reduced". This popup seems to "freeze" a bit the UI. I can't reproduce it reliably for now ... but it also stops me from using the buttons to change the output level - since it constantly appears. Not sure if the two issues are related though ..

PS: Tried also with 1.4-159, same result.

Thank you!
