    keyword=raster pickoff

    After Brad & Brandon fixed the cabling of raster pickoff, here are
    the signals in GeN DAQ. I've indicated the pedestal that was there
    before plugging anything in. It's possible that the pedestal shifted
    and that the strange peak is a broadened, shifted pedestal (??).
    Another minor problem is that we aren't using much of the 12-bit
    range. It might help to adjust the preamps to shift the signal
    away from pedestal and have larger gain to occupy more bits.
    Otherwise I have no idea ... looks strange ... should be flat.
