Every kind of EMC lab, explained.
Chambers, shielded rooms, test systems and the rules behind them, for anyone planning, building or choosing an EMC laboratory.
Types of EMC lab
Turnkey EMC labs
A complete EMC laboratory brings together chambers, shielded rooms, test systems, software and people. Turnkey means one team takes responsibility for making all of it work together.
Read more →Anechoic chambers
Radiated tests need two things: no outside signals, and no reflections from the walls. Shielding keeps the outside out; absorber deals with the reflections.
Read more →Shielded rooms
Not every EMC measurement needs a chamber. Conducted tests, control rooms and amplifier rooms need a shielded space without absorber.
Read more →Reverberation chambers
An anechoic chamber absorbs reflections. A reverberation chamber does the opposite: a shielded room with no absorber, where a rotating stirrer mixes the field.
Read more →GTEM and TEM cells
For small products, a cell gives a controlled electromagnetic field without a room-sized chamber.
Read more →Automotive EMC labs
Vehicles pack dozens of electronic units into a small space. Automotive EMC methods test each unit on a bench before it ever meets the car.
Read more →MIL-STD-461 and DO-160 labs
Government-program and airborne-equipment standards use their own methods, limits and set-ups. A lab built for them looks different from a commercial one.
Read more →Medical EMC labs
For medical electrical equipment, immunity is about safety: the device has to keep doing its job when the environment is electrically noisy.
Read more →Wireless and RF labs
Products with a radio have two sets of requirements: how well the radio behaves, and how well the whole product co-exists with everything else.
Read more →Pre-compliance labs
The most expensive EMC failure is the one found at the formal test, a week before launch. A pre-compliance bench moves that discovery to the prototype.
Read more →EMC test systems
Every EMC test answers one of two questions: what does the product emit, and what can it withstand? Test systems are instrument sets built to answer one of them to a given standard.
Read more →EMC components
A wrong filter or an unsuitable antenna can make a whole measurement chain unreliable. Components are easy to overlook and hard to replace later.
Read more →Accreditation support
Accreditation is granted by a national accreditation body to the laboratory. A supplier cannot give it; it can help the lab get its equipment, site and documentation ready.

Explainers
EMC testing: what it is and how it is done.
Electromagnetic compatibility testing checks two things: that a product does not disturb other equipment, and that it keeps working when other equipment disturbs it.
Inside an EMC testing lab.
An EMC lab is a set of quiet rooms, calibrated systems and trained people. Knowing what is inside helps you choose one, or plan your own.
EMC standards: a map of the main families.
There are hundreds of EMC standards, but most belong to a few families. Knowing the family tells you what kind of lab the test needs.
Electromagnetic compatibility, in plain words.
Every electronic circuit that switches a current also sends out a little radio energy, and picks some up. EMC is the discipline of keeping both within limits.
