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:
http://www.ni.com/white-paper/3983/en
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.

Julio,
can you please stop posting these one-liners. First of all, you’re
ignoring the etiquette of this list[1,2], which many consider impolite.
Second, a lot of your questions are either on the FAQ[3] (which should
be the first place to look) or the mailing list archives[4].

two other contributors had to get involved.Is there going to be a third time now?
No. This list member has been unsubscribed.

Julio -
You have started 20 new threads on the GNURadio list in the last couple
of weeks. Most of them are one-sentence questions that aren’t easy to
understand.The GNURadio community is in general very helpful, but you will get many
more responses if you first try to find answers on your own, then e-mail
the list with what you have done, and very specific questions to help
you
move forward.Please read this:

Cheers,
Ben

I may not respond a lot and only asked for help once but I do read a
majority of these emails and would prefer that this mailing list is
reserved for legitimate questions that could not have been solved by a
simple Google search.
