PXF for VCO PSRR measurement

    I am trying to setup PXF analysis to measure PSRR of a VCO. Cadence
    Appnote "Power Supply Rejection Ratio Characterization Using pectreRF
    Autonomous Circuits " states that
    modulated conversion should be used - what is modulation here & how
    does it work ?

    I am also not clear about Input & Output Modulated Harmonic List
    selections & why in case of modulated PXF analysis, maximum sideband
    is not that important - as the Appnote states.

    Please help...
