AD9789 Spectrum Mirrored by fc

When I input a sinus to the DAC, I see on the spectrum analyzer that  my tone is mirrored by the carrier frequency. Is this the expected behavior, e.g. NCO multiples the I path with sin(wt) and Q path with cos(wt)? If not, what might be my problem? And yes, I have checked the input connections.


Thank you in advance,
