CCFC RF noise
[Aritomi, Yuhang]
We measured CCFC RF noise (before demodulation after amplification).
Setting of spectrum analyzer: RBW: 300kHz,VBW: 10kHz
We used 50:50 BS to pickoff CCFC error signal and pump green power is 42 mW.
Note that CCFC and CCFC FC unlock were measured with max hold while others are normal setting. I think that's the reason why the floor noise level in CCFC and CCFC unlock are a bit higher than TAMA PD noise level.
