You might also take a look at osmocom_spectrum_sense, but the last time
I used it, I was suspicious of the results. I think it worked best at
no more than 10 Msps.
I really should have a better option for you considering that I gave a
talk on the subject last year:

Keep in mind though if the interfering signals are intermittent you may
miss them this way. 125e6 MHz of bandwidth is possible but takes some
expensive hardware Ettus X300 and a UBX-160 comes to mind. You could then
do the FFTs post processing if you needed more bin resolution then the
processor or an FPGA offload could handle.
If that application doesn't do it you could write some python to loop at
whatever bandwidth your rig will handle. If you wanted to get fancy you
could detect bins with energy and increase your dwell / focus in those
areas. A GNURadio flow graph to a SQL database would be quick and dirty way
to do this.

I've been asked to attempt mapping out a large band of RF (5.750 Ghz -
5.875 Ghz) to look for potential interference that might interfere with
video feeds on that band. I know none of my equipment (hackrf) has that
type of bandwidth to pull a real time fft, it will need to be pieced
together after the fact. I've been looking at trying this in grc after
seeing Balint do this with a USRP
but sadly my knowledge with grc isn't the greatest. My question is, does a
tool already exist that will allow me to do this outside of grc or is grc
the best solution for getting this running?
