Hello,

I am recently working with gnuradio's tx_samples.cc and USRP2. I have input files that are .sc type, which are written and saved on Matlab. I have a question though.
I've noticed that signals in the input files before being saved to .sc type are being scaled, for example:

signal = sin(A);
scale = 10000;

new_signal = signal*scale;

frwite(...)

Why do we need to use this scaling factor? 

Thanks!
