I'm going to have to get this Spectrum Analyser finished - then I can look at all this stuff!

Not sure I'm understanding what you mean above - do you mean the power at the centre frequency reduces (goes to the side bands). i.e. if I modulated a DC or very low frequency there would be no power at centre frequency the power would shift all into the sideband?

Cheers
