In the trunk (sorry, I didn’t take time to build 3.1.2), when I do> this, I see 16MHz of spectrum:> > [[email protected] ~]$ usrp_fft.py -8 -f 92.1 -d 4
How do you know you’re not getting +/- 8MHz?I am looking at the signal spectrum in Matlab. The window shows me, I belive, -Fs/2 to Fs/2. i.e. +/-8MHz, and the main lobe is covering just half of this range. I am using matlab command
where ‘data’ contains the IF samples. I can’t use usrp_fft at -d 4 coz
I am using a laptop right now. It gives me over run errors (uOuO). I
might need to try that on a desktop.
How wide is the signal that you want offset by 10MHz?
My signal is 20MHz wide and I do use ‘-d 4’ when I use usrp_rx_cfile
command. (Mistakenly, I forgot to put it in mail).
