Hello all,

I have faced another problem here. I am really in great trouble and want
this problem to be solved as early as possible.
I am using the usrp2_rx_cfile.py to get the raw IQ data in usrp2.
I am using the following command
sudo python usrp2_rx_cfile.py -f 800M -N 1000 -d 100 -s -v output.dat

After that, I converted the .dat file using octave command
(read_complex_binary).

However, the values I am getting are ambiguous.
I am getting lots of 0 (zeros) and lots of Nan (dont know what does it mean
though)..I have no idea about it.

Here is the snapshot of what I get. I would really appreciate if somebody
can give any idea about this. Thank you.
