Re: [Discuss-gnuradio] USRP1 gain

[Nemanja Savic]

Hi,

as far as I can see the only thing on wbx board that has adjustable feature in rx path is attenuator, everything else has fixed gain. Am I missing something here?

Best and thanks,

Nemanja

Ok, but as far as I have seen it is fixed and the only adjustable gain should be at PGA in front of the adc. Am i right?

Hi ll guys,

I am using for my application usrp1 and wbx board. From the documentation I got that maximum amplification value of 20 db, but in my flowgraph I am able to specify without problems more gain for usrp source block. If I put >20 db I really see changes in noise level, which means that something really happens. Can somebody say what happens for >20db gains, and why there is no warning or error when i tru o do that?

Thanks and best,
