Federico, Beatrice, Irene Bersanetti is ISC support in control room ITF in low noise 2 quiet 14:46 UTC 300s ENV_DT_MAG_COIL_CURR_MON using DAC and ADC in DetEER setup ready, Small coil on SDB1 tower base, axis EW amplifier on, set at max gain 1366643331 27 Apr 2023 15:08:33 UTC (27 Apr 2023 17:08:33 CEST) observe 1/f noise excess in magnetometer ENV_DT_MAG_* unplug amplifier from DAC 1366643443 27 Apr 2023 15:10:25 UTC (27 Apr 2023 17:10:25 CEST) 1/f noise disappears - it is DAQ noise DAC reconnected 1366643600 27 Apr 2023 15:13:02 UTC (27 Apr 2023 17:13:02 CEST) ADC ch 9 was noisy, moved ENV_DT_MAG_COIL_CURR_MON to ch 11. Tests with 21Hz line check mags and amplifier saturation 0.001 V to DAC 1366644492 27 Apr 2023 15:27:54 UTC (27 Apr 2023 17:27:54 CEST) 10 Hz 0.1 V to DAC 1366644770 27 Apr 2023 15:32:32 UTC (27 Apr 2023 17:32:32 CEST) 1 V to DAC 1366644937 27 Apr 2023 15:35:19 UTC (27 Apr 2023 17:35:19 CEST) still about a factor 4 before amplifier saturation 4 V 1366645092 27 Apr 2023 15:37:54 UTC (27 Apr 2023 17:37:54 CEST) 5 V 1366645167 27 Apr 2023 15:39:09 UTC (27 Apr 2023 17:39:09 CEST) think we are very close to saturation of the amplifier. We keep this as MAX voltage We observe coherence between ENV_NOISE_CEB_ and LSC_DARM... seems at calib lines... strange quiet - until 15:51 UTC colored noise injection from ENVnoise does not work !!!
