[Discuss-gnuradio] Quick question regarding plotting samples captured by usrp_rx_cfile.py against time!!

[Bishal Thapa]

Hi,
 I have a quick question regarding the complex binary samples captured by using usrp_rx_cfile.py. I would like to draw them against time. So, (Magnitude on Y-axis and Time on X-axis) in matlab. I was able to do the following

1. ./usrp_rx_cfile.py -f 2.5G capture.dat
2. d = read_complex_binary('capture.dat');
3. I was able to choose every other sample, because there are two samples per symbol. (Sample Rate =2). dd= d(1:2:length(d));
4. Then able to plot (abs(dd))  ---> This gives me magnitude (Y-axis) vs. Sample number (x-axis)
5. How can I draw these samples (dd) now against time(on X-axis).

Thank you for your time,
Sincerely,
