If you, for some reason, need that, you can either write your own sink that does that, or use python, octave, matlab, C, C++, or whatever you like to load the binaries and print out strings representing complex numbers textually. > so i use the usr_spectrum_sense. usrp_spectrum_sense is really a visualization demo. If you just want to save the signal from a USRP to a file, that's a two block flow graph in the GNU Radio companion: Just connect the USRP Source to a File Sink, parameterize both to your likings, and you're done. If that sounds strange to you, I can really recommend going through the guided tutorials 1, 2 and 3, and most of your questions will be answered :) http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials Greetings, Marcus On 12/01/2014 05:14 PM, Leo Yang wrote: > When u say complex samples, i thought it should in time domain, and after the > the fft block, it transfer to frequency domain.
