- What are we using 16 DAC channels for in the LSC?
|
For the new input and output tip-tilts. Two input, two output, each requires four channels.

- What are the functions of those IOO DAC channels which go to cross-connects? If they're not properly sending, then we may have malfunctioning MC or MCWFS.

I have no idea. I don't know what the hardware is, or is supposed to be, connected to. DAC for WFS?? Was there at some point supposed to be fast output channels in the PSL?

- Can we just use the SLOW DAC (4116) for the ALS PZTs? We used this for a long time for the input steering and it was OK (but not perfect).

Probably. I'm not as familiar with that system. I don't know what the availability of hardware channels is there. I'll investigate tomorrow. |
