12bit Oscilloscope Year 2025~2026 - Measuring accuracy this gets worst

[Kiriakos GR]

At 8bit Oscilloscope we knew 1.5% as measuring error tolerance.
Nowadays all newer Chinese 12bit Oscilloscope they come with 3.0% as measuring error tolerance.

In theory, digitizing at 12bit, this it should deliver cleaner from jitter signals, these able to be measured with increased accuracy, than the older digitizing at 8bit.

Something smells bad here, and no one bother so to investigate the reasons.

I can only speculate, that domestic production of 100% Chinese design of ADC, they suck big time.   
Chinese government this was and is, the main financial sponsor, so China this to develop and use exclusively made in China components.
   
From the other hand, I do not see the western public opinion, this to act with necessary responsibility, and to ban from it preferences all these equipment which come with inferior specifications. 

An Digital Storage Oscilloscope, this is not a screen so to watch movies on it.
It ends to be a plain marketing hook, the promise that low power signals they could be measured with greater accuracy, when actual scope front-end,  this comes with loosen measuring accuracy tolerance.

Its totally understandable, when such Chinese DSO products, they are made with inferior components, these not be able to deliver tight measuring tolerances.
This also explain the fact, of why all Chinese brands, they turned their back at independent product reviewers.

Since 2022 and this will continue and at 2026, China has no one at the western world, so them to talk to, when there is a new product developed.
My message to western youth and and hobbyist, you better stop asking around of why there is no product reviews about this and that.

China selected to walk alone, Chinese industries they follow the game dictated by their Chinese government, they have a major sponsor at their side, and they do not care of your money.

For western youth and and hobbyist, them aiming for a low cost oscilloscope, its wiser of you to research the market of used ones.
Anything this introduced at 2012~2018, this is still modern enough as a basic oscilloscope.

We are almost three weeks away from the New year 2026.

And another one Chinese brand, this select this specific period, so to present their inferior 12bit Oscilloscope. 
I am not against progress, the opposite, I would hope to see a true better priced competitor of Teledyne LeCroy scopes aiming professional use.

What I do see instead?
UPO1000HD: Education, portable test stations

Education =  Review of AWG generated waveforms.

Portable test stations =  Review of known waveforms = Testing


If there is a teaching, that an expert will deliver to first time Oscilloscope owner, this is just one.
All inferior gadgets they are marketed as made for education.
Such gadgets they are for your school to buy, and not for regular people to buy.

The real Oscilloscope this must perform two tasks successfully.
The real Oscilloscope this be compatible to measure voltage ripple this must be at 350MHz of bandwidth as minimum.
The real Oscilloscope this able to measure accurate PHASE difference of voltage and current waveform, this is not here yet.

Oscilloscope software decoding, this is cheap to implement, and nothing major as a feature.

In conclusion, due the fact that DSO operation this has a very short learning curve,  its a true waste of Euro coins, when these paying for a Low-End for education Oscilloscope.
The damage to your wallet this gets greater, when you will realize that there is no second hand market, for these scopes. 

Its hard to believe, but medium priced Oscilloscopes ( 1.500 ~ 3.000 Euros) they are more easy to sell them as used.
Simply because these are more usable from an Electronic repairs lab.

ITTSB this is full of proofs, that an 30 EUR DMM, and or an 300 EUR scope, these are classified as toys.

The problem from my point of view, Kids might be justified buying them, they are not aware that cheap food this is not good even for dogs.
But if I see such toys at the hands of a working Professional,  I do understand right away that this guy he does missing intelligence
