I think I’ve managed to do what you asked.
I got my function gen to do 6.1-13 in two decades x100 and x1000. The sweeps are almost linear after the first 500ms, meaning that each horizontal division of each 200ms denotes the following:
| Timemark | Frequency |
|---|

Well I guess, I’ve got a sweeping function gen and a 4ch DSO… I’m gonna look into that and get back.
Caveat: my engineering diploma in embedded electronics is 10 years old, and it’s been awhile since I’ve done more than just the odd solder job. So it’s going to take a little while.

@gondezee@lemmy.world when you say “plot a frequency sweep” what you’re looking for is just the usual voltage/time graph from a scope? No resistance in parallel to the capacitor for discharge? No fixed resistance in series? No x/y graphing funny business?
Or are you looking for a bode plot? I was hesitant in my first response because I thought I remembered Dave doing a bode plot with a sweeping gen and a scope, but I wasn’t sure if I could find it. I could m.youtube.com/watch?v=uMH2hGvqhlE
