#+TITLE: List of measurements

* 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

| Ty   | Ry   | Slip Ring | Spindle | Hexapod | Meas. file     |
|------+------+-----------+---------+---------+----------------|
| *ON* | *ON* | *ON*      | *ON*    | *ON*    | =meas_003.mat= |
| OFF  | *ON* | *ON*      | *ON*    | *ON*    | =meas_004.mat= |

| OFF  | OFF  | OFF       | OFF     | OFF     | =meas_008.mat= |

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)

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)

Channels:
| 1 | Ground |
| 2 | Ry     |
| 3 | Time   |

** From Ty to Ry
=meas_012.mat=
Everything off, one geophone on the Ty, one geophone on the Ry (measure on Z direction)

Channels:
| 1 | Ty   |
| 2 | Ry   |
| 3 | Time |

* New measurements 07/05

Low pass Filters at 1kHz are added before the voltage amplifiers

The voltage amplifiers are: 60db, DC(!) and 1kHz

Channel 1: marble motion
Channel 2: Sample motion

- All OFF =meas_013.mat=
- Ty ON   =meas_014.mat=
- Ry ON   =meas_015.mat=
- SR ON   =meas_016.mat=
- Rz ON   =meas_017.mat=
- Hexa ON =meas_018.mat=

* Test without the Hexapod Driver on the granite

- Hexa ON with on the ground meas_019.mat
