In elog2341, we reported the INPUT oplev was not set-up properly. I checked signal connection and found that input and output of SR560 were swapped. After solving this problem, INPUT oplev was recovered. (SR560 used gain as 100 and no filters) In the end, I compared INPUT oplev signals. Figure 1 shows this comparison, which shows a lower noise level.
