I am simulating phase noise with a spectre modulated pnoise analysis.  I can plot total PM noise at the output using Direct Plot, but I would like to know what noise sources are dominating.  Is there a way to calculate/plot the PM contribution of a particular noise source?  I know how to do this when noisetype=sources, but that gives the total AM+PM noise in one sideband.  I am interested in just the PM noise.  Does a modulated pnoise analysis have the information to do this?

Thanks,
