Measure of NEP and RIN(AOM on and off)

I noticed that the pre-amp of frascati works well. I report the NEP of the PDS 12599 and 12595.
Next step to measure the RIN increasing the power rispect to the measure of yesterday. P(12599) around 100 mW, P(12595) around 500 mW. I think that i can again increasing the power...
AOM OFF
AOM ON
The measure seem good.
I remember that this measure are to open loop. Next step will be to close loop and "to play" with parameter of the feedback transfer function for a minumum noise on both PDs. I noticed that with close loop the noise decreasing on both PDs.
