The test laboratory is investigating electromagnetic compatibility specifically for use in space applications. Plans for accreditation in 2016 are in place, which will enable EMC conformity tests to be conducted in accordance with MIL-STD 461F and ECSS-E-ST-20-07C. During the development stage, tests can also be carried out for other applications.

Service Range

• Testing of electromagnetic compatibility during the development stage
• Failure analysis of electromagnetic compatibility
• Support for the location and elimination of the source of failures

Test procedures covered by the system

The following tests can be carried out in a limited frequency range in accordance with MIL-STD 461F and ECSS-E-ST-20-07C. In addition, test receivers, wattmeters and signal generators cover frequency ranges of up to 40 GHz for future extensions.
