Re: [Discuss-gnuradio] USRP dynamic range / DBSRX measurements

[Firas A.]

Hi,

I think we are trying to do something different. We are trying to
investigate the possibility of increasing USRP dynamic range by modifying
some USRP FPGA stages. 
By the way, what was the equation used to calculate the ADC output in dB in
you graph?
