Hello,
I have a new USRP2 (no firmware upgrades), trying to run usrp2_fft.py
with a decimation of 4. I can run higher decimation values (-d 8, -d
16) but -d 4 brings up the fft gui and shows no signal. Sometimes I get
an ‘S’ but not always.
My computer is a Dell Optiplex 960 3.0GHz with 4G RAM. I am running
Fedora Core 11. The on board GigE is Intel 82567LM-3.
I tried ethtool -A eth0 rx on with no luck.
I have see the chart:
http://gnuradio.org/redmine/wiki/1/USRP2GigEReports
and my next step is to get one of these cards and try it instead of my
on-board NIC. But does anyone have other ideas? How fast a computer
should be fast enough? If people could list their PC
configurations/requirements, that would be great.
Thanks, all.
Hello all,
If anyone has run usrp2_fft.py with a decimation of 4, please let me
know what your configuration is…CPU, OS, GigE card, and any tricks you
used to get it to work.
Thanks for any help.
