Trouble with carrier suppression

I'm having problems with carrier suppression.  As an experiment, are there registers that I can manually set the DC offset of I and Q for TX2?  Are there registers I could look at that would give me a clue on what parameters I have set incorrectly or a calibration routine I should execute? I'm only getting about 20 dB suppression and expect 50.  The AD9361 is implemented in our CCA design and is not associated with your Xilinx test board.

 

Thank you for the help.
