[Discuss-gnuradio] DC offset and down conversion problems

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.
