Hello, I'm a newbie GNU Radio student, and I'm trying to measure the received signal power with an USRP2(using XCVR2450 as daughterboard and VERT2450 antenna). Setting up an ad-hoc network with two computers and using a third one running the GNU Radio flowgraph, I intend to detect the channel usage with the USRP2 while one computer is sending continuous PING messages to the other computer. To reach this goal, I designed the following graph:
[USRP2 source(f=5.2GHz,decimation=16, gain=46dB)]-->[Head(1024)]-->[FFT filter(taps=1024,decimation=16)]-->[Complex to Mag^2]-->[Number Sink] 1. The output of Complex to Mag^2 block, what is the data format (Watts, mW, dBm, dB)? 2. Why the gain parameter of USRP2 source block is between 0 and 92? What's the influence of this value to the measurements? Thank you for your help. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
