sampled PAC simulation

I am running a sampled PAC simulations on a comparator.

when I look at the output I see that the spectrum and sideband results are not the same. the sideband values are having the same trend as the spectrum for each harmonic but the values are about 3 time larger.

shouldn't the spectrum and sideband show same thing for each harmonics?

when I disable the sampled option in the pac I see that spectrum and sidebands are showing same results
