To get a scope/spectrum analyzer to work up to those frequencies, you need to sample at 1GHz (preferably higher). While that is perfectly reasonable, you cannot get that volume of data through a USB connection (even a superspeed one).
Therefore the best you can do is to get a separate scope/spectrum analyzer that does all of the sampling and processing and then passes the end results over to the PC.
Whether such a device exists or not I don't know but I would have thought that by the time you have a device that does all of that work, getting a stand-alone 500MHz scope/analyzer with a display and controls etc would be the way to go.
I have a Rigol scope that does all of that but up to about 100MHz that cost me about 750Euros (very rough currency conversion!) that I can connect to my PC to capture images etc, or dump them to an SD card.

I've seen Chinese ones at about 300-400Euros max at 200MHz but nothing higher than this.
I try to find a way to replace my HP 54520A, for space limitation reasons.
However these small box scopes/FFTs are way too expensive, whereas I bought the HP at 250Euros, great value.
