Hi Jim,
I am working on 950 MHz with 38.4 MHz IF. These are results for TSW34SH84 which uses DAC34sh84. After using GUI tabs, I am able to remove DC offset at carrier frequency ( shown at 0 in the following figures) and reduce I/Q imbalance shown at -38.4 MHz. Are you receiving similar results? you said you were able to remove carrier at 2042.1MHz, so D.C. offset at carrier frequency is removed I guess and you are dealing with I/Q imbalance product.
Can you give me your configurations and what you are getting? I also have DAC34sh84 module separately, which I am planning to start with soon, I can try your settings etc. and then see what seems to be problem.
It will be learning experience for me too.
Thanks,
