List of measurements
- Effect of control of each stage
- Measurement when signal from top geophone does not go trought the slip-ring
- Measurement from one stage to the other
Effect of control of each stage
| Ty on | data_001 |
| Ty off | data_002 |
One geophone is on the marble, the other at the sample location. The signal from the top geophone goes through the slip-ring
Measurement when signal from top geophone does not go trought the slip-ring

Meas009: everything off with signal goes through the slip-ring
Measurement from one stage to the other
From Marble to Ty
meas_010.mat
Everything off, one geophone on the marble, one geophone on the Ty (measure on Z direction)
=> Can be used to determine the vertical stiffness between the Granite and the Ty stage
Channels:
| 1 | Ground |
| 2 | Ty |
| 3 | Time |
From Marble to Ry
meas_011.mat
Everything off, one geophone on the marble, one geophone on the Ry (measure on Z direction)
=> Can be used to determine the vertical stiffness of the Ry Stage (by taking into account the Ty stiffness)
Channels:
| 1 | Ground |
| 2 | Ry |

From Ty to Ry
meas_012.mat
Everything off, one geophone on the Ty, one geophone on the Ry (measure on Z direction)
=> Can be used to determine the vertical stiffness of the Ry stage
