Rohde & Schwarz has the ZVA, but that's a two port unit while Keysight has 4. I haven't seen anyone else come close.

As for hobbyists... I'd love to hear of a hobby project that could make use of this.

Edit: Yeah, I'm thinking of the Keysight PNA-X which is a four port VNA. Still haven't seen anything come close to either offering, though.

The ZVA is an vector network analyzer, not an oscilloscope. Don't get me wrong, the ZVA is still an extremely impressive piece of engineering, but not even close to what Keysight had achieved with the UXR.

Derp! I got this confused with the PNA-X, which is a four port VNA that does 110GHz with additional heads. Thanks for the correction.

Remember, caffeine first, then internet.

The ZVA is not the same use case as this. The competitor to URX is the teledyne lecroy lab master which also has 110 GHz bandwidth. The difference is that teledyne uses bandwidth interleaving, which keysight argues is inferior (they are probably correct, keysight has some ENOB advantages, however teledyne has other advantages). Tektronix has essentially left the competition for this super high end, they didn't manage to go beyond 70 GHz (which was some years back for all of these)
