All, I'm trying to set all USRP and RFX2400 parameters comparable with Micaz in the context of receiver sensitivity. But I've observed a non-linear behavior of ADC.
By using usrp_fft.py, we can see noise floor level. When I change a rx-gain in a range of 0~45dB, noise floor level does not change. However, in a range of 45~90dB, noise floor linearly increases according to rx-gain. Does this affect receiver sensitivity? My thought is that high-gain of ADC introduces additional noise figure. Please give me a clue. Thanks in advance. -- View this message in context: http://old.nabble.com/Noise-floor-and-Rx-Gain-tp27288261p27288261.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
