Doesn't really look like a $20k scope to me. Guess the MSO stuff is on the back?
edit: they show the noise in that document
- 422uVp-p 50uV RMS at 50Ohm
- 871uVp-p 96uV RMS at 1MOhm
Make note that BW was not specified for those measurement.
10x less noise is also bogus claim.
Even if 49µV RMS was at full 1GHz BW, competition does not have 500µV RMS of noise at 1mv/div at 100us/div...
Also scope shows 3.2 GS/s with 1 and 2 ch enabled. I could not find image with 3 or 4 enabled.
It seems 100MPts/ch is max. (that is great improvement over old ones.)
