I applied the acoustic injection to REFL table
Injection : 1268580000 - 1268580110
DAC output 10000count 60-1000Hz uniform
silent : 1268579700 - 1268579900
I analized this data.
Background : 1268579800-1268579900
Injected : 1268579970-1268580070
Main channel : K1:CAL-CS_PROC_C00_STRAIN_DBL_DQ
Monitor channel : K1:PEM-SENSOR_BOOTH_IMC_BNC3_OUT_DQ
The 280 Hz bump and the 520Hz bump are well reduced. The 360Hz bump is still.
From a discussion with ASO-san and Nakano-san, the slope in 50-300 Hz may be due to that FF was not applied during this time.
