After getting converting factor (RIN-> freq noise) = 1.01 MHz/W. I plot the result below.

 The contribution to frequency noise in beat note from RCAV and ACAV due to RIN is calculated by,

fnoise = RIN x power input x df/dp factor. 

The beat note freq noise is plot on the noise budget.

Our beat frequency noise is not limited by RIN. I'll have to think what would be the current limiting source.

I'll check Megan's report about VCO and Marconi phase noise.
