If you mean
usrp_spectrum_sense.py and usrp_fft.py, then, usrp_spectrum_sense.py in Gnuradio/gnuradio-examples/python/usrp,
usrp_fft.py in Gnuradio/gr-utils/src/python/, if your install gnuradio is Gnuradio. Thanks, Kyungtae From: Marcus D. Leech

usrp1. I tried to test with usrp_spectrum_sense.py, however I am not sure the
power values measured is correct, because it is not same values shown as the
graph from usrp_fft.py. I wonder if someone helps me out for this. Thanks, Kyungtae _______________________________________________ Discuss-gnuradio mailing list address@hidden http://lists.gnu.org/mailman/listinfo/discuss-gnuradio Try building a little app using GRC
