High end state of the art spectrum analyzers from Keysight and similar companies can look at 1Ghz of bandwidth at a time and they cost upwards of $200k and take ~12u of rack space. RF is anything from 3kHz to 300Ghz. Unlikely that a $50 hobby SDR with 20Mhz of bandwidth is going to glean much of use unless you get lottery lucky.
