[USRP-users] How is gain distributed?

My N200+WBX reports a gain range of 38dB, which consists of 31.5 in PGA0 (a
frontend programmable attenuator), 6 in ADC-digital, and 0.5 in ADC-fine.

When I set the gain to a given value, how does UHD distribute the total
gain between the gain elements? I could not find this in the sources (I
could not even find the strings "ADC-digital" and "ADC-fine" in the UHD
sources; perhaps they come from the FPGA image).

Thanks, Sivan
