Hi James - Great feature! Best example I saw was a Hewlett-Packard lab where they built a full size shield room under the chamber turntable. If a DUT needed high cable count, or short length, or both, it was a great solution.
I'm adding a cable tunnel to my list - thx! -Patrick On Fri, Aug 8, 2025 at 9:52 AM James Pawson (U3C) < [email protected]> wrote: > Hi Patrick, > > > > The best modification we’ve made to our chambers is the addition of a > waveguide-like tunnel from the outside of the chamber under the shielded > floor to the centre of the turntable for customer cables. > > > > On our FAR it was 150mm x 40mm x 2000mm long > > On our SAC it is 100 x 100 x 3000mm long > > > > As soon as you put a cable in, even with loads of ferrites you see small > amounts of cellular radio on the emissions plot but we know to watch out > for this. > > > > For a commercial laboratory the ability to cater flexibly to a wide range > of customers cables, coolant hoses, fibre optics, etc is invaluable.
