Subject: RC frequency noise 

 I changed the gain setting on SR560 to find how it will effect the noise floor of the RC noise.

It seems that the gain and the cutoff frequency do not alter anything at lower frequency (below 100Hz), but they

change the position of the peak around 1kHz.

I'll find out noise from SR560 and the PD to see if their noises are dominating in this f.
