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

Honored ContributorI have already inverted sign bit and is outputing a wave fine. The issue is when frequency sweeping the amplitude is changing.
Is there any files for the frequency response of the DAC? I mention the ADC as I guess it will have a similar issue when feeding a signal back into the card.
