TJ, Camilla. At 15:20 to 15:37 we drove CO2Y PZT at 80Hz and then 45Hz using H1:TCS-ITMY_CO2_PZT_OUT_GAIN_EXC via awggui, see attached. This was to check that we could drive a line using the CO2 PZT that we can later use to inject noise into DARM to understand if in future we'll need to re-install the CO2 ISS (Aidan started T2200341). Hope to repeat with H1 locked later.

Also saw that that CO2Y power meter that is measuring power injected to te IFO saw more lines than CO2X when no excitation was driving either PZT, see attached.
