We changed the filter setting for CCFC to remove the peak at 170Hz. The new filter setting is 30Hz LPF and gain of 1000.

Then we measured FDS with CCFC (attached figure). The peak at 170Hz disappeared with the new setting.

Unfortunately, I couldn't find the anti squeezing quadrature. We will measure it again.

Degradation parameters:

sqz_dB = 10.5;                    % produced SQZ (dB)

L_rt = 120e-6;                    % FC losses

L_inj = 0.35;                     % Injection losses

L_ro = 0.24;                      % Readout losses

A0 = 0.05;                        % Squeezed field/filter cavity mode mismatch

C0 = 0.05;                        % Squeezed field/local oscillator mode mismatch

ERR_L =   1e-12;                  % Locking accuracy (m)

ERR_csi = 30e-3;                  % Phase noise (rad)
