Rigol announces "serious" scope: DS70000

Sample rate is a deal breaker for me.  1 channel at 20Gs/s ok, but it drops to 10Gs/s at 2 or more channels?  No thanks.  I think all of the Keysight and Tek keep full rates for two channels at least.

The motorized tilt thingy seems like a 'sizzle' feature that is pretty pointless in actual useage.

You may want to check the footnotes in the specs: Sample rate reduction works the same way as in most four-channel scopes: As long as one channel of a "Group" is active, sample rate stays at 20G. A group is channel 1+3 and 3+4. So you can have two channels sampling at 20G by using a single channel of each group. Same for the sample memory.
Martin72:
Infinivision 6 scopes got max 20GSa/s, which will be reduced to half when using all groups, therefore same behaviour as rigol.
Tek scopes, lecroy scopes will do the same.

Ah, OK.  That is a puzzling thing for them to call "single channel mode".  But I stand corrected. 

Martin72: yes, I am aware of how most scopes work for sample rate.  None of those OEMs call using two channels at once "single channel mode".  I can live with 2 channels at max rate rather than 4 or 8.
