But then how do they get 2 GSa/s out of that? Unless the 800/900 are artificially throttled...

I don't know really. Maybe it is throttled, or it might just be a bad guess. But, why would they make a model like the 1000u if not for BOM savings? (and lowering the price)
Assuming everything else is the same (frontend, screen, ADC, etc), it looks like the most sensible approach.

TomKatt:
Can't find much info on the HDO1000U series - are you even certain it offers the same 2gbs rate ?

I don't know if the U model will launch in Europe, but maybe they are discontinuing the DHO1000? With the Black Friday promotion and all.
Right now, at $600 plus $300, if you know how to desolder and solder the ADC, a 1074 could be turned into a 4804 for less than 1k, bar the active probe interfaces.

Looks like a downgrade from the DHO1000 series: Half the memory size (25 MPts standard, 50 optional) and a reduced waveform capture rate (max. 30k/s regular mode, 500k/s UltraAquire mode).

If it has the big screen and 2GSa/sec. then it could be worth a look...
