[Discuss-gnuradio] DC offset and down conversion problems

[Shih Oliver]

Hi,  

I'm using the lfrx board and try to turn off the DC offset correction but it seems no change in the data collected.

I'm wondering if I did it wrong and here's part of my code: 

       self.uhd_usrp_source_0 = uhd_usrp_source()

       self.uhd_usrp_source_0.set_auto_dc_offset(0, 0)

Also I am trying to do a down-conversion on the USRP source to 

get the I Q. So I set the center frequency on USRP source, but the result  I get is really weird. 

Is there anything else I should do or I just get it wrong.

Thanks for your help in advance.
