Hi All, i think i have a misunderstanding, but i don't know where it is.
I tried out an example named <usrp_am_mw_rcv.py> with a Hardware Signal Generator connected to my USRP. My Signal Generator generates a sin Signal with 7.0711e-3V effective at f=1.05e6 Hz. So my power is, P = U*I = U^2/R, with I = U/R P = (7.0711e-3_V)^2/50_Ohm P = 1e-6 W Now we convert this into dB, P_dB = 10 * log10 (P/P_0), with P_0 = 1W p_dB = -60_dB But my measured Power is -11,933_dB so what is my Problem ? Any Hints ? The example can be found in, /usr/local/share/gnuradio/examples/usrp/usrp_am_mw_rcv.py Regards Markus _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
