Output amplitute from an NCO

Am i right in thinking that the output amplitutde from the NCO is not constant over different frequencies?

Hard to say. you better give more details about your design from NCO to DAC to the way you see amplitude. Do you use any fft?

You can exclude NCO by looking at max/min mif values per each sweep point.
