- checked that the high voltage paths are working:
- the DAC signal is properly received and amplified by the Trek 2220 HV amplifier
- the HV switch box is working as expected: I can switch on and off each path individiually using the DAC signals
- installed four samples (refer to the optical drawing for the numbering)
- S1600472 in bay 1
- S1600478 in bay 2
- S1600473 in bay 3
- S1600480 in bay 4
 
- balanced all samples and centered all optical levers. There is a problem with the fifth connector in the ADC interface board (or maybe with one ADC channel). So one of the quadrants of QPD4 was not working. I moved the connector to number 6 and updated the model. Everything looks fine now.
- the power in the four QPD is quite diverse: this is not unexpected, since it depends on the interference of the reflection from the two surfaces of the disk

- installed the picomotor controllers on the bench, connected them to the net using the switch on the top of the clean room. For the moment being they are using DHCP.
- connected all picomotors to the controllers.
- Bottom controller, from left to right: QPD1x, QPD1y, QPD2x, QPD2y
- Top controller, from left to right: QPD3x, QPD3y, QPD4x, QPD4y
- tested the remote control and motion of all picomotors
