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

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	ON	ON	ON	`meas_005.mat`
OFF	OFF	OFF	ON	ON	`meas_006.mat`
OFF	OFF	OFF	OFF	ON	`meas_007.mat`
OFF	OFF	OFF	OFF	OFF	`meas_008.mat`

Meas009: everything off with signal goes through the slip-ring

meas_010.mat Everything off, one geophone on the marble, one geophone on the Ty (measure on Z direction)

Channels:

meas_011.mat Everything off, one geophone on the marble, one geophone on the Ry (measure on Z direction)

Channels:

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

Channels:

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
