Dear fellows, I am using USRP with d'board Flex 2400 to transmit and receive a wideband signal. My target frequency (carrier frequency) is flexible and could be anything within the d'board range 2.3 to 2.9 GHz. I am trying to set DDC at zero frequency. Non-zero DDC may have some unwanted effects (not sure here!). I am using usrp_siggen.py script with my own signal generation program. When I looked at the output of 'tune' function the DDC never goes to zero (by reading dxc_freq). I tried using different target frequencies at the command line of usrp_siggen but dxc_freq never went to zero.
BTW, I understand the two step tuning process but I was expecting that for some target RF frequency dxc_freq should be zero. If this is not possible, I will explain my concerns about the non-zero DDC for wideband signals. Any help/pointer is highly appreciated.
