I compared the results of the swept sine acoustic injection tests at the MCF area, performed on May 14.
The first figure is the 0-1000 Hz range and the others are their zooming up.
- 50 counts (orange) vs. 200 counts (green) of the DAC output, 100-120 Hz scan with 1 Hz steps
- The results are almost similar for all frequencies. the green could project for a wider frequency range.
- Around 120 Hz, 220 Hz, 340 Hz, and 520 Hz: The current sensitivity looks to be occupied by this acoustic noise.
- Probably these projections have double counting with the REFL results, because these location are close each other.
