 I'm working on using GNU radio to receive and process GSM signals.  In
 looking at the usrp_rx_cfile.py program, it appears that the DDC's MUX value
 is set automatically by probing the USRP.  In our case it sets the MUX value
 to 0x1.  We think that means that the ADC1 input is wired to the signal I
 value on DDC0 and the ADC0 is wired to the signal Q value on DDC0.  Is this
 correct?
 

Yes, it is.


 Thanks,
