"North" current driver having slow current fluctuations |

I dug through the log to figure out what created the 8s noise in the current driver. I suspect it was my power cable connectors on Feb 3 , but it seems Rana measured this clean beatnote spectrum on Feb 4. Still, all other changes were downstream of the current drives -- was the broken current driver involved in that clean beat?
I've added another datapoint of the laser frequency noise from my measurement Jan 25. |
