Rigol announces "serious" scope: DS70000
Martin72:
Ja, die dedizierten Knöpfe hauen es raus.. ;D
Sorry for the german... ;)
Me, I got no problem with non dedicated knobs as I was always used to use them on lecroy scopes for more than 17yrs.

But not above.
In the past, there were 500Mhz or more scopes with less samplerate as 2GSa/s avaible and still usable, so no sweat.

Yes but we need remember SDS2504X Plus is only specified as offering 500 MHz capability for 2 channels not 4 and they need be assigned to each ADC to maintain 2 GSa/s so not to challenge Nyquist.
RTFM. ;)

"only"...Very good. ;)
I don´t need rtfm, why, read the post again.

I know you know but Noy has missed this. ;)
SDS5000X with dual 5 GSa/s ADC's at 1 GHz still meets Nyquist with 4 channels active.

I seriously doubt that. Although I don't know much about the SDS5000X, the SDS2k with 500MHz BW does not filter the signal much up to 1GHz and shows plenty of aliasing if pushed. But IMHO that is OK, if you know what you are doing and the scope has more BW limiting options for the frontend (like the SDS2k). But "meeting Nyquist", not so much...
E.g. the SDS2k with 500MHz bandwidth can comfortably measure a 800MHz signal ;)
