Hello
I wonder someone can help me out. While testing this code, the media with the
different size of fft shows different value. I would like to know how I can get
the same media value regardless of using different fft size.
Thanks,

Firas,
have to written a detailed explanation about "usrp_spectrum_sense.py" ? I
am unable to find it. Please let us know the link for the same...

Hi everybody!
I have modified usrp_spectrum_sense.py to plot the results with gnuplot.
There are two files: widespectrum.py and plot.p
I would like everybody to test it and report me the errors and how can I
improve it.
I've used USRPv1 + Flex2400.
Thanks in advance!
Here it goes...

Please see the Python tutorial. It and lots of other good
*USRP_SPECTRUM_SENSE.PY*
How can I use the *self.max_freq* and *self.min_freq* like a global
variable?
I want to use it in the *def main_loop(tb):*
but if I use it
*That's the given error:*
*Traceback (most recent call last):
File "./spectrum_output.py", line 309, in
main_loop(tb)
File "
I obtain this plot from 2.23GHz to 2.90GHz (with a Flex2400) but I
don't know how to put the correct frecuency on the x axis.
Because if I put this:
g('set xrange[223000:29]') # I can't see anything!
To plot I have done this:
g = Gnuplot.Gnuplot(debug=1) # Out of the while loop
g

Yes, OR, you can wait for me to write a detailed explanation (may be in two
weeks) about "usrp_spectrum_sense.py".
I think the understanding of this program is very important
ok, so I have to modify this program to show in a Frame the results I want,
haven't I?

See usrp_spectrum_sense.py, it implements this technique to scan the entire
spectrum available to each USRP daughter
Yes, but I think we can take the spectrum of every 8MHz band and put it into
the computer so it can memorize and show it.
Sorry for my english...

santi, such a wide frequency range is not possible due to limitations
in the bandwidth between the usrp and the host
currently you give usrp_fft a center frequency and a decimation rate,
and from that it calculates the start and end frequencies...

"If you think you're too small
Hi!
I need help to modify the usrp_fft.py file to show the spectrum of a input
range (for example from 2.3GHz to 2.9GHz)
