New toy(?) scope Fnirsi DPOX180H, claimed 180MHz/500MSps (May 2023)
csuhi17:
I was impatient and before the ordered capacitor arrived, I unsoldered the old ones because I was interested in what it was like.
It also gave me a value of around 330pF. and not 740
Unfortunately, I couldn't find any rev. number on the board.

Well, after reading this and the DSO2512G’s thread entirely, I have decided to go with Zeeweii’s offering. It costs a bit less, but it seems to have better functions and less issues than the DPOX180H. I hope I won’t regret it :) Thank you everyone for your suggestions.

you won't, but keep in mind that the zeeweii doesn't have a 20MHz bandwidth option, it's always at full bandwidth.
But it's way better than this unfinished toy fnirsi

A little challenge for all owners of fnirsi like myself :palm:
set FG to 1KHz Square Wave, 2 Vpp, 50% duty
press Auto
Press H+ until H=1us (top indicator) watch the glitch
Keep pressing H+ until H=5ns watch the amazing and wonderfull waveform :palm:
Fnirsi, fnirsi, naughty and wild boy!
Bellow 32KHz is useless, we can't trust anymore on the displayed image if we zoom in (not zoom button)

The good thing is: You learn to make your own low-pass filters for the Zeeweii. For a penny and an egg. ;)
