2*pi*2A/lambda = 1.00e+11[cnt/m] = 3.00e+14[cnt/strain]
- 11:35 Open loop transfer function measurement
- template diaggui /users/CAL/PHASE1/templates/DTT/T_OPTF.dtt.xml
- 1st measurement : /users/CAL/PHASE1/measurements/DTT/T_OLTF/T_OLTF_180428_114110.xml
- 2nd measurement : /users/CAL/PHASE1/measurements/DTT/T_OLTF/T_OLTF_180428_115610.xml
- 3rd measurement : /users/CAL/PHASE1/measurements/DTT/T_OLTF/T_OLTF_180428_124641.xml
- 12:15 Coil driver transfer function measurement
- transfer function measurement between coilout and FC
- EXC(K1:VIS-BS_TM_COILOUTF_H4_EXC) MEADURE(K1:VIS-BS_SCMON_TM_H4)
- Be careful, channel name is including SC, but connect to FC.
- ??:?? Modified calibration model(C00 Strain)
- z-8 delay between error and control
- optical gain
- Discussed about unknown time delay (1block:1/16384=61usec)
3 known block delay : LSC->BS, DAC, LSC->CAL?
- aAA, dAA, aAI, dAI
- iKAGRA has 130usec unknown delay...
- ??:?? Start Open loop transfer function measurement
- with envelop, measurement accuracy becomes much better!
