Agilent has sampling oscilloscopes that work up to 100 GHz and has recently rolled out real time scopes that work up to 30 GHz, but they cost like 250K. Spectrum analyzers covering 100 GHz have existed for more than 30 years.
I'm not up to speed on what the differences are between a sampling o-scope, real-time o-scope, and spectrum analyzer... Nonetheless, it sounds like a spectrum analyzer may exist for the sort of frequencies the OP is looking for, although possibly not something cheap and easy that he can plug into his computer.
