Since we don't know the specs of 15.2MHz EOM, we wanted to check the 15.2MHz sideband power. Yuhang estimated 15.2 MHz sideband power from p pol PLL.

 

103MHz (beatnote of ML carrier and p pol): -30.61 dBm

87.8MHz (beatnote of ML 15.2MHz sideband and p pol): -58.67 dBm

 

Power ratio of ML carrier and 15.2MHz sidebands (both sidebands): 2*10^(-28.06/10)=0.0031.
