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!

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.

Anyone know if there's a way to dim the screen on this thing? I'm sure default brightness would be great for daylight but when just testing something quickly of an evening it's damn bright. Might make the battery last a bit longer too.

When I wanted to buy the DSO-TC3, the videos I watched on YouTube were quite downgraded, so I didn't order one.
Does "HF rejection" work for anyone in the trigger menu? I don't see the effect.
Also, the HardBandwidth limit at CH1 does not seem appropriate either.
Shouldn't the frequency above 20Mhz be completely cut off?
For me, it reduced the 60Mhz signal from 800mV to 400mV. the slow 20kHz signal was not modified.
Is it possible that the error could have been caused by the fact that I replaced the capacitors?
RAPo:
I've got a message from Fnirsi with this download link.

RAPo What's the point my friend, you already tested V4 and it's worse than what we already have!
