[ Mirko, Koji, Suresh ]
Looked into the modulation frequency that should pass the input MC. With a locked MC looked at the RF output of the PD in refl of the MC. Looked at the beat between 11MHz and 29.5MHz. Minimizing it by fine-tuning the 11MHz freq. ( which means maximizing the 11MHz transmission).
SB freq. [MHz] Beat power [dBm]
11.065770 -80 (diving into spec. analyzer instrument noise)
11.066060 -80 (surfacing out of spec. analyzer instrument noise)
Set the freq. to the middle of the last two points: 11.065910MHz at 16:26.
ToDo: How big a problem is the AM?
