It looks like a standard atomic physics setup with a vacuum system and a bunch of lasers. Definitely not built to be portable. The performance is quite a bit worse than conventional semiconductor based RF spectrum analyzers which can be carried around. Maybe they have some ideas how to improve it in the future. Currently it is clearly just a proof of concept that shows that Rydberg atoms can be made sensitive to broadband RF at all.
