quiet
21:14:43 UTC  to 31:31:00 UTC

NOTA: hrec looks very noisy while LSC_DARM seems ok

**** test sweep with different speed 

NEB
sweep 5V 30-100 Hz 300s
21:31:00 UTC - 21:37:34 UTC
(a few missing data at the beginning) 
can see something in DARM

sweep 5V 30-100 Hz 1200s
21:39:18 UTC - 22:00:00 UTC
glitch a circa 21:40 UTC
can see it in DARM

sweep 5V 30-100 Hz 600s
22:02:16 UTC - 22:15:32 UTC
glitch at about 22:05:40
can see it in DARM

**** test linearity by injecting lines with different levels
