SHF spectrum alanlyser

Hello

I am interested in scanning from 1000 MHz to 1200 MHz

Can the USRP and gnu radio down convert and show me a spectrum ?

Second question. Can the USRP be used to sweep filters ?

You can use the USRP as a spectrum analyzer, but you’ll need to keep in
mind how it is different from a standard spectrum analyzer. First, it
does not sweep. It will take snapshots of the spectrum up to 8 MHz wide
on the USRP1 (25 MHz on the USRP2). If you need a wider picture than
that you will need to step the center frequency. The amplitude is also
not calibrated to the degree that an expensive analyzer would be.

Sweeping filters could probably be done, but it is not that common of an
application for us.
