Chris B, Joe B
After LLO had locked again, Joe and I took the opportunity to perform the coherent stochastic injection. CW injections were off at both sites. And the intent bit was off at both sites.
For the LLO couterpart aLog entry see: LLO aLog 21999.
Waveform:
The waveforms injected were: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/stoch/Waveform/SBER8V3.txt
Injection:
At H1 Chris performed the injection with the command:
awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 SBER8V3_H1.txt 1.0 1129673117 -d -d > log_stoch.txt
I've attached the log.
As we were doing the injection we noticed a range drop of ~10%.
IMPORTANT ACTION ITEM:
The end of the stochastic waveform was not tapered. So when the injection ended it introduced a large transient into the ETMY. Robot voice was activated. This needs to be fixed. The beginning was properly tapered.
