First of all, due to my mis-understanding, the left light source, which was set the temperature, heater and battery power supply(Yesterday) was connected to PF YPL oplev.
And right light source was connected to MN YPL oplev. So please ignore any suggestion for the MN YPL oplev glitch noise investigation
Now, the left light source is for MN YPL oplev, center source is for MN YRT oplev and right source is for PF YPL oplev
Then, again, I set the battery type of MN YPL light source and start the measurement.
During this work, I sometimes touched the light source , then, glitch occurred. And when we turned off another light source, glitch also happened.
So I suspect there are several type of glitches. And we will check it one by one.
Finally, I checked the spectrum before and after changing to the battery power supply.
(The 60 Hz power line issue would be reported by Washimi-san later)
We checked the waveform of the AC power.
The AC for MN oplev looks to be deformed a little, but not so much.
