It would be nice to make a comparison like this.
Without doing the test I expect the Agilent to produce more wfm/s, they're using selfmade ASICs which are faster than FPGAs.
We've got many Agilents in our company beginning with the old 54622D scopes, the DSO6034A to the really very expensive
high end models - they all have in common to have fast ASICs.
But wfm/s is not the bottom line buying a scope - and the memory of the DSO2000X is simply to small for many purposes. Because of that
even the DSO2000X is an expensive scope compared to both Rigol type series.
If Agilent, better start with DSO3000X instead of DSO2000X. So I came to the Rigol DS4012 instead of buying the DSO2000X, would do it
again immediately.
