Last night the sensing matrix for IMC WFS&QPD were measured.
C1:IOO-MC(1, 2, 3)_(ASCPIT, ASCYAW)_EXC were excited at 5.01Hz with 100 count
The output of the WFS1/WFS2/QPD were measured. They all looked well responding
i.e. Pitch motion shows pitch error signals, Yaw motion shows yaw error signals.
The below is the transfer function from each suspension to the error signals
MC1P MC2P MC3P
-3.16e-4 1.14e-2 4.62e-3 -> WFS1P
5.43e-3 8.22e-3 -2.79e-3 -> WFS2P
-4.03e-5 -3.98e-5 -3.94e-5 -> QPDP
MC1Y MC2Y MC3Y
-6.17e-4 6.03e-4 1.45e-4 -> WFS1Y
-2.43e-4 4.57e-3 -2.16e-3 -> WFS2Y
7.08e-7 2.40e-6 1.32e-6 -> QPDY
Taking the inverse of these matrices, the scale was adjusted so that the dc response.
