Yes, this is a recently launched ATSC 3.0 capable System Analyzer. It also does analog, ATSC 1.0, satellite and cable, and includes a 3.3GHz real time spectrum analyzer as well as a host other features: Fiber, Radio analyzer, Wi-Fi analyzer, IPTV measurements, long etc.
Just go to free You Tube search and type Hexylon Interface, or type Gsertel and this will bring up neat video clips on how to operate the handheld spectrum analyzer.
Nice looking gadget, looks like Star Trek technology level!
One site lists the H30Evolution at an MSRP of $1,200 so I'd imagine the Hexylon is considerably higher (probably talking T-BERD territory here).
"Handheld" may be a little optimistic for the Hexylon as it is about 8-1/4" tall x 9-7/8" wide x 2-3/8" thick and weighs 4-3/4lbs. The spec sheet calls it a "portable".
