Hi Charlie - Great set of ideas ! Thank you, Patrick On Fri, Aug 8, 2025 at 12:08 PM Charlie Martin <[email protected]<mailto:[email protected]>> wrote: Here are a couple of thoughts: - What the purpose of the chamber: immunity, emissions, compliance or pre-compliance, and to what standards. -Think ahead for flexibility: for new standards, future frequencies, type of absorber, low loss antenna cables maybe up to 26 GHz… -If on the ground floor, maybe its own ground rods to separate from the building’s ground for ground loops and interference, dielectric breaks, isolation transformer without a power ground… -Ventilation with honey cone vents, lighting with feedthroughs -Fire codes: no sprinkler heads, indigene gas suppressant, smoke alarms. - A one-foot drop floor: is nice for access to cables, to turn table (EUT cables to the center via 4” PVC pipe), the antenna mast, patch panels and or waveguide pipe, future flexibility… -Cameras with zoom and sound -Support needs for compressed air, nitrogen gas, water, LAN, I/O cables… -Attached to chamber a control room for test and support equipment. Include a place to hide!

ATTENTION: This email originated from outside of the organization. Please do not open any attachments or click any links unless you recognize the sender and know the content is safe. 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 !
