Print this reportAcoustic injection test Xend and YendI performed the acoustic injection test using the swept sine measurement at Xend and Yend
06:00 - 06:30 test of the awggui for the swept sine injection Please use the data before 6:00 JST for the reference
06:30 - 07:00 swept sine acoustic inejction at Xend Low frequency 50 Hz High frequency 300 Hz Rate 1800 sec Gain 300 count Excitation channel K1:PEM-EXCITATION_EX0_RACK_1_EXC
07:06 - 07:36 swept sine acoustic inejction at Yend Low frequency 50 Hz High frequency 300 Hz Rate 1800 sec Gain 300 count Excitation channel K1:PEM-EXCITATION_EY0_RACK_1_EXC

Print this reportI performed the quick analysis using the pastavi.
0. Reference (00:00 - 00:32 JST ) (Fig.1.)
1. Swept sine acoustic injection to Xend (Fig.2.) We can see several linear coupling in above 200 Hz, but no significant excess below 200 Hz.
2. Swept sine acoustic injection to Yend (Fig.3.) We can see linear coupling in 280, 250 Hz, around 11o Hz
