blue: the currently implemented one
red: which would be tested, the plan (dcdamp_test) Maybe I want to have infinite at lower frequency region.

[ ] BFGAS loop、dcだけなら閉じる?
[Note] the spectra are same, just see the right hand side:
data: /users/VIS/TypeA/general/LogNotes/20190924/ITMX
At around 7h30, TF measurement at the BF-sateg was done: /users/VISsvn/TypeAtower/ITMX/Measurements/20190926/
According to TF, the shape was smae as the previous measurement which was doene on Junuary 2019. However, dc loop looked NOT working as expected and high frequency noise (> 500Hz?) looked injected. => why?
2019.9.26, I finished with
Background
ITMXのBFのspectraに0.25Hzのピークがあった。
loopみてみたら理解できない形のものがあった。like:
これ、どういう思想?
これ、ここから入ってくるノイズが0.25Hzのソースの可能性あるのでは。
ほかのsuspension 大丈夫?
