We measured modulation index of f1 of EOM2a with sweeping frequency of RF signal( see the plot).
-shut out delay line and b-path of 1st MZM
-take beat note with 1st refraction beam of AOM
In this measurement, the voltage on the EOM can be assumed like the following.
(Distribution amp) + (RF amp) - (Attenuator) - (Cable loss) = 13[V] + 17[V] - 7[V] - (Cable loss)
We will measure all the modulation indices tomorrow.
