Green and Infrared error signal
Today I finished the measurement of green and infrared error signal. The delay is because of the inappropriate use of spectrum analyzer. So notice to use the unit of V/sqrtHz next time. Now we have solved this problem. I attached the result here.

I also attach the txt file here. It has not been calibrated yet. The calibration factor I used here is 2.6e-3 V/Hz(for green), 170Hz/V(for infrared).
