In order to find out whether electronic or electrical systems and components function satisfactorily
in a certain electromagnetic environment, various conditions can be simulated in the EMC test laboratory
of the DLR Institute of Space Systems in Bremen and the emission of electromagnetic interference can
be determined with the help of emission measurements.

The EMC laboratory of the Institute of Space Systems examines the electromagnetic compatibility of
electronic or electrical systems and components for space applications to determine whether they function
in a specific electromagnetic environment without emitting unacceptable electromagnetic interference.

The constant and flexible availability of the EMC laboratory, as well as the close integration with other
facilities of the Institute of Space Systems - such as thermal laboratory, mechanical/dynamic laboratory,
electronics laboratory and integration hall - are particularly useful for the development of hardware within
the DLR, as integration, qualification and verification remain within one institute. A wide variety of test
systems are also available to accompany new developments over short distances.

CE Conformity Measurement and Tests (pre-compliance only)

All tests listed here can only be carried out during development, because not all test conditions according to
DIN can be implemented in our laboratory in accordance with standards, but are implemented using
representative measurement setups.

• Measurement of conducted emission on power supply and signal lines
• Measurement of radiated electromagnetic field emission
• Test of susceptibility from radiated electromagnetic field
• Test of susceptibility to fast electrical quantities (burst) on power supply and signal lines
• Test of susceptibility high-energy surge voltages on power supply and signal lines
