We swapped CMS for PLL-X and PLL-Y each other.
Now S1809501 and S1809505 are used for PLL-X and PLL-Y, respectively.
After preparing the PLL version of a new CMS, we will replace S1809505 which is noisy.
Fig.1 shows PLL spectra before (X: magenta, Y: cyan) and after (X: red, Y: blue) swapping CMS.
MIXER_DAQ of X get quiet and one of Y become noisy now.
The MIXER_DAQ of X became quiet, and the MIXER_DAQ of Y became noisy.
We will monitor whether the oscillation around 300Hz, which sometimes occurred on X, will appear (or hopefully vanish) on X or Y.
