Confirmation about sine wave equation of NCO IP Core

I tried plotting the following sine wave equation from page 3-1 of NCO IP Core User Guide v14.1 into an excel file. s(nT) = Asin[2π(fO+ fFM)nT+ ϕPM+ ϕDITH)] I also generated...

Thanks!

But what I am trying to say is that it seems that the Altera NCO Time domain graph always results to half of the value of the sine wave equation from page 3-1 of NCO IP Core User Guide when I tried to plot it in excel.

Am I missing something on this? I'm confused because I expected the two to be the same since it is said in the user guide that the generated sine wave by the NCO IP Core is defined by the equation s(nT) = Asin[2π(fO+ fFM)nT+ ϕPM+ ϕDITH)].

Thanks!
