I am testing Daqarta, a very complete oscilloscope that works on PC using the audio board as input.
I measured directly on the power pins to see the waveforms. Here they go, the first is an spectral analysis and the second a oscillogram .
Someone did the same tests? I think it is a good start to see the performance of the PSU that we are using.
It would be very useful for me to know the opinion of someone specializing in these matters.
