I'm looking at a really noisy signal on my yellow channel. Annoyingly noisy as the chip's analog power has an LC filter so it's SUPPOSED to be quiet, but that's not your problem. I notice the background is colored a faded yellow kindof following the trace. What does the background mean? I figure you wouldn't have drawn it dark yellow if it didn't mean something. Perhaps, "this signal is horribly noisy!" It is that. (It's also like a 10th the amplitude I was expecting.)
