You´re right, it must be a failure in the description.
But apart from that, nice scope..
And only siglent knows why they´re offering two vertical resolution models. ::)

Hello,
yes very nice scope and I think they mean 220 μVrms at 4 GHz.
 
Cleverscope CS328A even had three different resolutions on offer:

"CS328A   4M Samples, 10 bit sampler, 8 digital inputs, USB I/O
  The CS328 can be upgraded to 8M memory and 12 or 14 bit dual channel sampler, plus signal generator."

Red Pitaya was also once available with 10 or 14 bit

Best regards
egonotto

Me thinks you need use a different translator:
main features
Bandwidth: 4GHz, 3GHz, 2GHz
Memory depth: up to 1Gpts/channel
Vertical resolution: 12-bit /10-bit
Real-time sampling rate: up to 20 GSa/s
Waveform capture rate: up to 1 million frames per second
Low noise floor: as low as 220 μVrms at 4 GHz bandwidth

I know there is peoples who do not think money because from wall you can get more but there is still peoples and companies who may think also money...

But still we can see one single bit more do not double price but it doubles resolution.
And even more, here we get 2 bits more and we get quadruple resolution with same frequency bandwidth and samplerate.

It is totally different case if we reduce  samplerate (and BW) when we rise resolution. This is why.
Not because they just want to be uncomfortable.

Of course, everyone also understands how the market works, as well as why pay more if you don't need more.

12 bit, SDS6204 H12 Pro   2 GHz,  ¥229,880  Normal model
10 bit, SDS6204 H10 Pro   2 GHz,  ¥139,880  Economy model

The same realities are affecting the model SDS7kA as well.
and this 100 xxxx/s  need translates as 100*10000 and all who understand chinese numbering system and these "words" know it. But some translators perhaps not. When chinese say something what heards somehow as "millon" it is 10k (10000) and many times example prices are told in "millons" example in house markets. It is 10k not 1M.
