Subject: nb with VCO noise at 10khz input range 

I got Marconi noise data from Frank, and plotted it on the noise spectrum to show that we are limited by LO noise at high f.

Note that I use old RIN approximation as Frank suggested that  RIN noise and beat noise have a same feature.

 

I plot marconi noise with 100kHz input range and compare it with the bea noise with 100kHz input range, on fig2.
