Maybe I'm crazy, but that doesn't look like PSK to me. It just looks like a really noisy serial bus.Does the OP have any more questions at this point?
I think I agree with you. Not about the being crazy part.... but PSK wouldn't have regions of no signal in between those 'pulses', right? But....then again, at the same time, I'm getting a bit confused about the initial opening post showing USB signaling, and then there's the green waveform photo about 'PSK'...... not even sure where it is measured. Not sure where the connection is.
