Notes and Changes:

-v3: First approximation to four channel version by Mark B. See four_chan_sat_amp.PrjPcb . I renumbered all the components to correspond exactly to the LIGO schematic. The parts that will need to be cloned to create the four channel version have been isolated on sheets cs1, ps1 and etc1. The interface sheet has a suggested configuration of connectors, but the gender needs to be decided. The several DE-9 connectors that correspond to J4 on the LIGO sat amp (all the diagnostic outputs) should probably be combined back into one large connector. I need to check that all the Altium parts used have appropriate package sizes that correspond to the components in the BOM.
