I measured AD-FMCOMMS2-EBZ TX single tone performance@2GHz. At maximum output, atten=0, scale =0.5. The SFDR is about -60dBc, and also find spur at CF+/-88K(-55dBc) and CF+/-320KHz(-65dBc). Is this performance can be improved?

I set the DDS in One CW Tone mode,and set both tx1 and tx2's single tone frequency is 0. Is this turn off the internal DAC? Is the output come form internal LO? If that's the case, does that mean the result I measured Is the LO's performance? and what limit its performance?
