Re: [Discuss-gnuradio] query regarding store transmitted signal

Hi Maitry,

If you just want to store and load after with GNURadio you can use file sink and file source directly as Markus said. Just set the output and input type correctly. The data format is "stupid" binary so the samples are written as is on the disk, so it also does not matter what happened before signal processing wise.

If you want other formats I'd suggest to write a converter in python, you can easily convert to csv or Matlab readable files like that.

P.S.: .DAT as a file ending does not really say what format it is. Actually, you can name your file in GNURadio whatever you want.

Cheers,
Jonas

Hello,

Thanks for your reply.

I.e It is possible to store the transmitted modulated signal (for ex AM modulated signal) through USRP as per below, USRP source - file sink. but in which format, this data can be stored? (.txt, .pdf)_ I have seen.DAT file in one of the example,but when I tried , it does not give proper output.

Actually, my requirement is to receive the modulated signal through USRP source, store it in a file. and later, I can be able to do demodulation offline from that particular stored data. it will be grateful, if you provide guidance.


With Best Regards,
Maitry Raval,

Hi Maitry,

sorry, we have no idea what lab you're referring to! However, yes, that sounds exactly what File Sinks are meant to do.

Best regards,
Marcus
