Print this reportMeasuring data for testing the offline noise subtractionTo investigate the offline noise subtraction, especially non-linear noise subtraction, we added the oscillation to PR3 mirror and took data
Before this measurement, I measured the DARM OLG, as shown in Fig.1.
data1 : PR3 pitch oscillation Date : 2023/06/22 05:17:00 - 05:47:00 (JST) To record the main oscillation siganl, we injected the line signal from BPC model. K1:BPC-PIT_PR3_OSC_FREQ = 490.1 K1:BPC-PIT_PR3_OSC_CLKGAIN = 30 Fig.2. showed the spectrum during measurement You can find the oscillation signal in K1:VIS-PR3_TM_DRIVEALIGN_P_OUT_DQ
data2 : PR3 yaw oscillation Date : 2023/06/22 05:50:00 - 06:20:00 (JST) To record the main oscillation siganl, we injected the line signal from BPC model. K1:BPC-YAW_PR3_OSC_FREQ = 590.1 K1:BPC-YAW_PR3_OSC_CLKGAIN = 30 Fig.3. showed the spectrum during measurement You can find the oscillation signal in K1:VIS-PR3_TM_DRIVEALIGN_Y_OUT_DQ
data4 : PR3 pitch oscillation Date : 2023/06/22 06:51:10 - 07:20:10 (JST) To record the main oscillation siganl, we injected the line signal from BPC model. K1:BPC-PIT_PR3_OSC_FREQ = 590.1 K1:BPC-PIT_PR3_OSC_CLKGAIN = 30 You can find the oscillation signal in K1:VIS-PR3_TM_DRIVEALIGN_P_OUT_DQ
data5 : PR3 yaw oscillation Date : 2023/06/22 07:21:20 - 07:51:20 (JST) To record the main oscillation siganl, we injected the line signal from BPC model. K1:BPC-YAW_PR3_OSC_FREQ = 490.1 K1:BPC-YAW_PR3_OSC_CLKGAIN = 30 You can find the oscillation signal in K1:VIS-PR3_TM_DRIVEALIGN_Y_OUT_DQ
After this measurement, I requested to OBSERVATION state
