Hi, At 436MHz with a gain setting of 76dB, NF of 5dB, BW of 2MHz, I expect the noise floor of the B210 to be around -174+5+10*log10(2e6)=-105dBm
When I run the SDR Console software, this is what it appears to be. If I feed in a 1MHz wide AWGN noise source at -100dBm, it can be seen 5dB about the floor. However, when I try to capture the same data using the MatLab USRP interface or the rx_samples_to_file program (with same gain and sample rate), the noise floor seems to be at around -90dBm. (E.g: rx_samples_to_file.exe --duration 1 --rate 2000000 --freq 436e6 --gain 76) Any idea why this might be? Possibly something silly, but I can't seem to figure out what.
