NEXIO Laboratories (EMC / Radio / Near field)

EMC and RADIO test laboratories in Toulouse, Grenoble and Paris
NEXIO is also an electromagnetic design office with several EMC and RADIO test laboratories based in Toulouse, Grenoble and Paris.

Operated by experienced consultants on a one-off (daily) or integrated basis, NEXIO laboratories enable you to provide rapid answers to questions concerning :

  • Comprunderstanding and characterization of EM phenomena
  • Development and integration of RF functionalities
  • Application ofhe 5 golden rules of EMC design
  • Anticipating constraints and risks
  • EMC and RADIO evaluation, tuning and pre-qualification
  • Investigation and compliance
  • CE marking and support for export markings (FCC, etc.)

When the assignments entrusted to us involve support through to certification, NEXIO can count on privileged partnerships with a large number of notified laboratories in the automotive, aeronautics, space, military, rail, medical, industrial, IT, multimedia & telecom sectors, etc.

Laboratoires Nexio services

We have built up a team of over 80 technicians, engineers and PhDs, capable of integrating EMC into a project approach, designing and building the product’s EMC, or validating the product’s EMC behavior.

We provide expertise and support for technological choices, design assistance, investigation, digital simulation, technical documentation, qualification…

tests carried out under conditions close to certification conditions, but in optimized configurations.

Webinar: 5 key steps to successful EMC certification

Key steps to successful EMC certification :

Whatever the type, size and complexity of the electronic equipment under development, EMC management is a matter of managing risks, costs and development time.

In this presentation, NEXIO consultants will share the 5 key steps for embarking on an EMC certification process with mastery and serenity.

They’ll show you why managing these constraints is much simpler than it seems, as long as you take them into account methodically from the very first hectometers of your projects.
