[Discuss-gnuradio] LO of the USRP2 motherboard

[Jorge Miguel]

Hi,

 

I have an easy question.

When I use my basic T/Rx daughterboards I can tune the receiver to an specific frequency. Since the basic T/Rx doesn't have any LO, I would like to know where is physically that LO in the USRP2 motherboard. I cannot find anything in the schematics. Where is it? Is that LO the one which translates from IF (coming from the daughterboards) to real base band?

 

Thanks in advance,

Jorge
