SDSU (ARC) CCD controller documentation

10 May 2017

Following Dave Atkinson's visit to Thailand, we realised that the documentation for ULTRASPEC is in a dire state. To rectify this, Dave collated the following set of circuit diagrams and user manuals for the CCD controller boards in ULTRASPEC, as well as providing a change history document. Note that all of the drawing versions should now be correct with the exception of the power control board (ARC73). Bob Leach doesn’t have any 6B documentation on file, but he suggests that 6C will be as good as "identical".

I've now also added the circuit diagram for the SDSU PSU (ARC80) that we use for both ULTRASPEC and ULTRACAM.

ULTRASPEC has the following boards in its 6-slot chassis:

The drawings and manuals for the various SDSU boards are below:

We also have a complete set of spare boards. Here are their details:

SDSU PSU: We use an ARC80 (large) PSU for ULTRASPEC, as well as for ULTRACAM. The circuit diagram for this is given here: ARC80_Sch.pdf
