Noise spectrum of pitch and yaw RF signal of QPDA1,2 in MCe urad is attached. During this measurement, COACH was ON.
Red and blue curves are pitch and yaw RF signals of QPDA1,2. Green curve is pitch and yaw signals of MCe oplev.
Peaks at 4 Hz in yaw signals are calibration peaks which show the calibration is correct.
Noise level is 2-4 orders of magnitude higher than the actual MCe motion, so we cannot close the control loop of WFS.
