EMC tests

Evaluate the electromagnetic disturbances on your equipment thanks to EMC tests.

Electromagnetic compatibility (EMC) testing consists of verifying the ability of electrical or electronic equipment to function satisfactorily in its electromagnetic environment without itself causing electromagnetic interferences that are disturbing to everything in that environment.



The range of EMC tests offered by Sopemea can be used to test the compatibility or resistance to waves of a product, equipment, system or infrastructure. Sopemea carries out : 

  • Emission tests: the disturbances generated by the equipment under test are measured and compared with normative limits or manufacturers' specifications.
  • Immunity tests: the behaviour of the equipment under test is analysed when it is subjected to disturbances of a type and at levels defined in standards or manufacturers' specifications.



The range of tests offered by Sopemea is as follows:

  • Conducted emissions from DC to 400 MHz
  • Radiated emissions: magnetic field between 0 Hz and 30 MHz and electric field between 10 kHz and 40 GHz. (Anechoic chamber and MSRC)
  • Conducted susceptibility (BCI: 10 kHz - 500 MHz) up to 3 A
  • Radiated susceptibility (10 kHz - 40 GHz) up to 30 kV/m
  • Lightning Indirect Test (LIE)
  • Lightning Direct Effect tests (LDE) with generator providing up to 200 kA
  • Electrical tests on power supply networks ("on-board network")
  • Electrostatic discharge tests
  • Radiated and conducted nuclear electromagnetic pulse (NEMP) tests
  • Radio tests
  • DRAM tests (Electromagnetic radiation damage to weapons and ammunition)
  • DREP measurement tests (Electromagnetic Radiation Hazards to Persons)
  • Zt parameter measurement tests (transfer functions)
  • Shielding effectiveness measurements (GAM-T20 and IEEE 299)
  • Specific Absorption Rate (SAR) - contact AxesSim, our Electromagnetic Simulation Department 

An exeptional range

of testing facilities

At each of our sites we have all the necessary equipment to meet your EMC test campaign needs.

Sopemea can use semi-anechoic or reverberating chambers to conduct these tests. We can test vehicles (up to 500 m³) with exhaust extraction. Our cages are equipped with isolated and adjoining measurement rooms to ensure a suitable testing environment.

Sopemea is also the only private entity in Europe with a direct current effect lightning generator up to 200 kA. With a test area of 3 m x 2.5 m x 2.5 m, expandable on request, we are able to apply A, Ah, B, C and D waveforms alone or in combination. [Video Demo]

All external equipment of an aircraft or any military system can therefore be lightning qualified in the Sopemea laboratory in Toulouse. Thanks to the LG200k, it is also possible to evaluate the direct effects of lightning on any structural element: metallic or composite panels, windows, etc. _

You can watch the AeronewsTV report on the extension of our lightning generator in Toulouse:

We also have a mobile MSRC which allows us to carry out all types of tests directly on the customer's site. We can reach levels of over 6 kV/m in high field tests on the customer's site by this means. (Width: 5.5 m, Height: 5.2 m, Length: 6 m)

The available facilities (electrical power, 50Hz/60Hz/400Hz electrical network frequencies, hydraulic pressure and flow rate, etc.) allow these tests to be carried out on equipment in its operational conditions.

The tests are carried out by qualified engineers and technicians.
