Hi @attila,
Interesting. In reviewing the plot you shared and in reviewing my original description/question I realized that perhaps I am asking the wrong question. Does the software automatically include some kind of analog plot/data that is always overlayed with the logic plots similar to what you are showing?
From my exposure to logic analyzers what we are really interested in are just High (H) / Low (L) thresholds (1.8V, 3.3V, 5V, etc... normalized to 1 or 0 etc...), the time base scaling, and perhaps in more fancy or advanced analyzers the protocol/decoding. Based on the plot you shared would it be reasonable for me to infer that the analog data is what is is throwing off the logic plots (Y scale?) ? Since we are only interested in 0 or 1 like levels if analog 0 to 255 is overlayed 0 to 1 gets drowned out no?
The Analog Discovery 2 / WaveForms software is proving difficult for me to lock into (zoom in/out) to my logic signal in any kind of expedient or easy way. I have to search pretty hard for the signal and even when I ultimately find it it is not so pretty in scale, timebase, and packet from a visual point of view. I am sharing a couple of plots from my other logic analyzer software that hopefully provides some sense of what I am attempting describe here.
The output is from a UART TX line at 115200bps. Scaling the time base keeps the protocol decode/text displayed nicely and the signal zooms in/out centered around the mouse pointer for example. Very easy to zoom and pan and read the text no matter the time base and no matter where I am in the signal. The signal is instantly displayed this way the instant the channel is enabled and I dont have to spend much time getting it dialed in for viewing. I have yet to discover if I can do this in WaveForms.
