In any case, you should make sure the RF noise floor just overrides the quantization noise floor of the ADC, but no more. Fine tune to maximize the SNR (the blue bar graph on the right).If not, increase the gain by an extra notch. Check that increasing the gain no longer increase SNR.Increase the gain until the natural noise floor rises by about 5dB.
The following fine tuning procedure ensures you have the maximum SNR on the signal of interest while preserving the dynamic range: The “Linearity” mode is the one you want to start with: As depicted in this screen shot, there are many gain modes: Then next step is the gain configuration. Then run SDRSharp.exe and select the “AIRSPY” front-end: Airspy was designed by the same people who developed the SDR# software so it’s the obvious choice for running Airspy and leverage all its powerful features.įirst, go to the download page and get a copy.
