Hi, All
Someone the calculation the Resolution Bandwidth (RBW), USRP2 + RFX900
with and usrp2_fft.py ?

You'll generally find when communicating with other sentients on this
planet that questions asked should generally be in the form of
complete thoughts, with enough surrounding context to make a coherent
answer more likely. I realize that English is not your
first language, but unfortunately, most people here are English
speakers, and struggle to understand your questions.
I *think* what you're asking is about the effective RBW of an FFT-based
spectral display. There are notes here:

Which you could have found with Google in about 10 seconds.
Really, the RBW of an FFT-based spectral display is:
input-bandwidth/FFT-length
That has nothing to do with your hardware or even your software, but
rather is just an essential, emergent truth of the way FFTs work.
