These are done with an Analog Discovery 2 instead of a scope but similar examples exist for scopes.  The Siglent SDS1104X-E is supposed to be capable of reproducing these plots but I don't have one.  It would also require an compatible external signal generator.

The first is a Bode' Plot of the frequency response of an RC low pass filter (0.1 ufd capacitor, 10k resistor), the second uses the same components but looks at the forced response.  Look at the capacitor charging waveform out toward 6 ms (the RC time constant is 1 ms so 6 time constants is essentially full charge).  Finally, there is a plot showing the current waveform leading the voltage waveform in an RC circuit.

These are the kinds of plots I wish I could have gotten back in school.  Alas, the slide rule was king of the day.  Today, every EE student should have an AD2.

Agreed!
However, I actually need the data, not just screenshots. Are you able to export the data to a csv?

So I did a long single shot of the linux SOC booting up which captured several seconds of UART data. I saved that to file. All the files SHOULD be of the same data. I suspect the CSV was cut down to low resolution. I'm not familiar with the other formats but being how large they were I figured they were higher resolution.

I will recapture later today and see if that helps.

Awesome, thanks so much! Yeah, I'm not sure what's up with that, I've been reading into how the Rigol .wfm format works and it's quite simple. It will be relatively trivial to import it into Octave. The .csv is definitely made up of fewer samples, assuming the .csv and the .wfm you put in that zip were the same capture (which I'm assuming they are).
Cheers and thanks again!

Attached are new captures from the UART. I took the captures at various timing scales. The screenshots should align with what is in the CSV files.

Awesome! Thanks for uploading this. I've already been using it to write some of the demos for this "class". Cheers!

Hallo,

MrAureliusR: "not just sitting at 0v"

Sorry but the noise from a scope my be interesting.

noise_1M_16.mat: Noise from a 16 Bit scope
sinus_2M_16.mat: Sinus from a 16 Bit scope
noise_1250k_12.mat: Noise from a 12 Bit scope
sinus_1923077_8.mat: Sinus from a 8 Bit scope
sinus_1785714_12.mat: Sinus from a 12 Bit scope

The format is MATLAB 4. Octave can handle this format
