1) for PSS,   whtat the "output harmonics/number of harmonics"mean? For eample, for number of harmonics=20, does it mean the simulator takes into accout the 1st to 20th harmonics of the fundamental frequency or only the 1st to 20th harmonics of the fund will be output??

2) for PAC, Pnoise, Pxf, what does maximum sideband mean?  

3) for Pnoise, what does reference sideband mean?

4) for the noise summary get from noise/Pnoise analysis, is the spot frequency relative freqency or absolute frequency?  

5) When use PSS to simulate a mixer, both the LO and the RF are seen to be Large siganl, but it's said only one signal in PSS in treated as large signal while the others are small signal. So what really happens in PSS simulation?
