It seems there's another new high-end scope on the market, this time from Rohde & Schwarz.

As its predecessor, it claims a waveform update rate of up to 1M wfms/s, and offers 16bit vertical resolution via an optional 'HD' mode (software-based).
Most notably is the larger screen, 12.1" WXGA (1280x800) instead of the 10.4" XGA (1024x768) display in the predecessor. This will certainly a benefit as the RTO UI is very flexible and can display a lot of information, which on the smaller screen sometimes lead to overcrowding.
The RTO is an interesting scope, especially since it's supported by the R&S Vector Signal Explorer (VSE), a vector analysis software similar to Keysight's 86000B VSA. VSE can run on a separate PC or directly on the scope.
I haven't found any prices yet but I guess we're roughly at $18k for the basic 600Mhz 2ch variant.
