Hi, All,
I am a bit confused about RSSI calculation.
I can see RSSI is defined by 16 bits.
But in usrp_prims_common.cc, function usrp_read_aux_adc,
*value = ((v_hi << 2) | ((v_lo >> 6) & 0x3))
<< 2; // format as 12-bit
the value is only assigned by 12 bits. I though the value is
RSSI. But then it contradicts with format given in the verilog
code. Or value is not RSSI?
Any help is appreciated.
Fengyuan

I believe that the aux adcs are only 12-bit resolution.
