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. I know using a BW of 25MHz is a lot of data, but was hoping to at least get the fft working.
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 (to double check my flow control) with no luck.
I have seen 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?
If you have successfully run usrp2_fft.py with -d4 can you please list your PC configurations/requirements?
Thanks, all.
