[Discuss-gnuradio] Can I use uhd_fft or gnu-radio to display the spectrum with adjustable frequency resolution

[LD Zhang]

I am trying to use the uhd_fft or gnu-radio scope in a way that it can show a real-time spectrum but with adjustable resolution. The uhd_fft spectrum resolution appears to be fixed and not changeable. The gnu-radio scope block only puts out time series but not real-time spectrum. What is my way out of this situation?

 

Thanks,
