Output amplitute from an NCO

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

I have checked the clocks and can confirm that it is the same clock for both of them.

I am trying to find out more about the ADT1-1WT componet that is on the board. As i know I cannot produce Freq of under 1Mhz as this is acting as a high pass filter - which I can live with.

But I think it is definately doing something to my amplitude as I change frequency in the range 10Mhz to 45Mhz.
