ETMX ITMX Angular Excitation -- for Keita

Alexa, Daniel, Sheila

 

RED TEAM: We are exciting ETMX, ITMY Pit and Yaw over night.

 

I have excited ETMX, ITMX Pit and Yaw, L2 test filters at various frequencies. The oplevs move from around .2urad to .5urad. In this configuration the green lock transmission ranges from 760 counts to 400 counts. Increasing the drive caused the arm to lose lock (and we assumed Keita wanted to make his measurement with the arm locked), and caused ITMX suspension to trip. Hopefully, this set up is enough for Keita's measurement. The start time was around: 8:34:52 UTC time. The excitations are being run by four awggui's on opsws7. I have attached the awggui configuration and a picture of the oplev motion on dataviewer.
