The input of the adc is between 0 and Vref (i don't
know this value). The gain and the offset are to place the input value
between V- and V+ (this values are chosen by you). The decimation step
down the sampling frequency. I know the operation of the verilog block,
but i don't know how to program some new values because i don't understand
pyhton at this time. If you want, i can send you a block schematic of the
top of the FPGA to help you to understand.
Can this help you?

Understanding the various relationship of gain, decimation and offset values
in the captured file USRP.
I am a bit trying to understand the
relationship of the gain,offset and decimation parameter in the USRP and
what it reflects in the capturing of the files ... If i want to get a
proper output of a particular frequency with proper
output how can i adjust
Althou i do realise my question / doubt may be a bit different or may
be unrealistic and the way i asked my
question may be a bit Ambigious..
please do tolerate it and also ask me if so , so that i can make it more
Thanks guys in advance....
