GNU Radio

Hi all,

I want to read aux_adc of AD9862 to get the RSSI value.But when I read
the
code of method usrp_read_aux_adc, I am confused.
The aux_adc of AD9862 is 10-bit. Why is the result of usrp_read_aux_adc
formatted as 12-bit.

It was done this way to allow for the use of 12-bit converters in the
future.
