ADC setting parameters are not used for the USRP B210. You can use
"satnogs_other_settings": "type=b200, PGA0=31.5",
"satnogs_rx_samp_rate": "26e6",
Why so big rx_samp_rate? It should be noted that the dynamic range and sensitivity of SDR depend not only on the number of ADC bits, but also on the ratio of the sampling frequency to the signal bandwidth after digital processing. The processing gain is defined as
where Fs is the sampling frequency, BW is the bandwidth of the useful signal. This is because, in digitized systems, ADC quantization noise is distributed over the entire Nyquist/Kotelnikov bandwidth, which covers frequencies from 0 to f/2. If the signal bandwidth BW after processing is less than f/2, then the system filters remove the noise components of the processed signal outside the useful signal bandwidth, which reduces the total noise energy and increases the signal-to-noise ratio. Theoretically, the spurious free dynamic range (dBFS) is: SNR = 6.02N + 1.76dB, where N is the number of ADC bits (72.24dB for 12 bits). For example, if after sampling a signal with a width of 200 kHz at a frequency of 26 MHz, decimation is performed, then the processing gain will be 10 * log (26000000 / (2 * 200000)) = 18.13 dB, and the resulting dynamic range for SDR with a 12-bit ADC will be 72.24 + 18.13 =90.37dB.
