Worked on getting the rejection ratio for the Fast GVT at different temperatures. This involved setting the shaker/accel/laser head up inside an environmental chamber. Brad suggested mounting everything on a large rigged mass so that it would be very stiff, thus not causing any modes in the frequency range of interest. I did this but you could still feel the vibrations on the stand, being transmitted to the laser head. This being the case, I mounted the laser head on the side of the inside of the oven. This gave a good RR.
I also talked to Paul J. about the interface box that would house all the circuitry and control boxes. He suggested using a 19" rack, and having Card Racks mounted in these 19" racks that would hold the PCBs. This way you could easily source the needed power to a group of PCBs. He also suggested that we have multiple interface boxes that could be stationed around the plane so you would not need incredibly long cables to run to the accel/laser head.
