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. It gets used almost every day!
All the best
James

*Subject:* [PSES] Design a chamber from scratch- what are your top 5
features?
Good morning.
I have the opportunity to design an EMI chamber from
scratch. I'm generating a list of all my loved features, and hated
features.
Here are a couple that come to mind.
_Loved_: abundance of overhead lighting
_Hated_: lighting only with flood lights in upper corners
_Loved_: replaceable bulkhead passthrough panel
_Hated_: all of the bulkhead panels at ankle height
If you were building, what is your love/hate feature list?
(spoiler alert- I will copy your ideas into my design!)
Many thanks !
Patrick.
