instead of solving the problems this model has, they insert the "old" one into a new dress and try to fool everybody into buying another one with the same bugs

this is not a bug, this is a feature
I don't know how legitimate this method is.:
Fnirsi's sampling is 500Ms/s, i.e. there are 2ns between two samples.
The storage/memory depth is 120kp, that is, if you make a single shoot in 20us/div from a 50Mhz color signal, it should be smooth.

But if you zoom in on it

There is 10ns between two points and the total length of the signal is 20us*12div, that is, it is only 24k samples.
If you don't watch it in 20us/div, but in 200us/div, you will see it better with a 5Mhz signal.

I couldn't insert the picture into the text, 16 belongs to 18 and 19 to 20
A 15 year old entry level scope like the 1052E has all those trigger features, I assume it's not a hardware limitation? Guess there was just no budget for the software to add these things to ~100EUR scopes or they wanted to keep the UI simple?
I've tried it, and I'm going back to the previous version:
-with no signal, the measurement bar is updating several times a second with nonsensical values
-the scope becomes very sluggish both in auto mode and pressing keys.
It takes almost a second to update after a V+ press,
pressing H+ gives a truncated trace for a second, only then refreshes.

Fixes:
1: The thickness of the waveform is reduced, making the waveform thinner and clearer.
2: The vertical lines of the square wave are brighter and more obvious
So just some further tweaks to the waveform display. Haven't tried it, but better than nothing, I guess.
Hello, I received my DPOX180H a few days ago. I really thought I bought a good portable oscilloscope for the money and I became convinced to buy it by all those reviews on YouTube that praise it so much. Of course reading this thread, makes me have a lot of doubts whether I should start using it as I cannot accept that a device you tend to depend upon so much for certain type of troubleshooting, can perform so poorly. People here are even talking about a hardware mod (the two smd capacitors) to make it behave somewhat more reliably. No, until a proper firmware is out, which I admit I'm doubtful if this ever happens, I'll put it on a shelf out of sight. As if this oscilloscope wasn't a bad enough experience, today I received the FNIRSI DSO-TC3. I had bought it mainly because of its build quality, which is better than your standard Chinese 20 Euros device. My main use for this device would be the ESR meter. Guess what, everything works except of the ESR meter. It treats every capacitor as having practically no internal resistance, the perfect capacitor! Others have also recognized the problem but not the YouTube reviewers! It came with V0.3 of the firmware and I don't know if this is the culprit or whatever. Very disappointed by FNIRSI!
there's no V4 on fnirsi website, maybe it's beta version?
RAPo What's the point my friend, you already tested V4 and it's worse than what we already have!
Don't believe in all youtube reviews, the majority are from people who get paid or receive free products from manufacturers, like influencers (liars) and that's what they do, lie to you so that you click and buy.
The scope is nice for some tasks, but for others no way.

it is possible to downgrade?
what about "transparent menus" in new version? can be adjusted now?
