The laboratory is dedicated to support ESA projects and European Industry by providing measurement and test services in the field of:
Our EMC engineers are qualified to operate the lab and to provide test services as well as troubleshooting and consultation for projects and R&D activities. The lab also enables hands-on activities for staff, young graduate trainees, and stagiaires. The support delivered from the lab enables projects to ensure EMC aspects are addressed already early in the development and throughout all the design phases, thus avoiding Electromagnetic Interference (EMI) problems on the flight hardware.
Services provided include:
The EMC test facility is equipped with state-of-the-art test and measurement instrumentation. The EMC test Facility can be used in the frequency range from DC up to 40 GHz and is equipped with test and measurement instrumentation for conducted, radiated and ESD tests.
It provides services for highly demanding non-standard tests as well as for standard EMC tests on electronic units, equipment and subsystems including consultation, test execution, reporting, and troubleshooting.
The EMC test Facility consists of a shielded anechoic test chamber and a shielded control room, providing controlled environmental conditions. The anechoic test chamber is equipped with pyramid foam absorbers on the walls and the ceiling while the floor is covered with ferrites. In the control room as well as the test chamber, test tables with a copper ground reference plane are available.

The Mobile Coil Facility (MCF) provides services for rotational measurement and multiple dipole modelling of the remanent magnetisation of units under test, in near-real time, using advanced non-linear optimisation algorithms. It can also be used for the measurement of induced magnetic moment as a function of the applied field (up to 100 μT) and for the magnetisation and demagnetisation (perm / deperm) of parts and units, compliant to the ECSS-E-ST-20-07C. The MCF enables missions requiring tight magnetic cleanliness control (Swarm, BepiColombo, Solar Orbiter, JUICE, LISA).
The MCF consists of two pairs of squared Helmholtz coils for the open loop compensation of the ambient magnetic field, one pair of perm/deperm coils connected to a 4-quadrant amplifier, four 3-axis magnetometers (100 μT range), a turntable with motor drive and a computer for command, control, data processing and production of automatic test reports. During rotational measurements, the magnetometers are oversampled synchronously at a typical 10 kHz frequency; the signals are then filtered and decimated to obtain an angular resolution of 1 degree and an effective amplitude resolution in the order of 100 pT as inputs to the optimisation algorithms.

The AC Magnetic Facility allows the determination of low frequency magnetic emissions in time and frequency domain. The powered unit under test is placed fixed in a volume defined by 8 or 16 magnetometers and the facility software can discriminate between magnetic sources inside or outside this volume using spherical harmonic expansion models and Gaussian separation into inner and outer sources. This allows rejecting ambient noise substantially and enables verification of demanding requirements for science missions, such as JUICE. The frequency spectrum is derived from the time series, thus the lower limit on the frequency range is mainly driven by the acquisition duration required to capture the relevant operational mode changes of the unit under test.
The AC Magnetic Facility provides equipment to measure very low quasi-static magnetic fields in the frequency range 0 - 50 kHz and to predict the amplitude spectrum at the point of interest, e.g.the location of the sensitive instrument on the spacecraft. The AC Magnetic Facility can either be used with a set of 16 triaxial fluxgate sensors (DC - 2 kHz) or with a set of 8 triaxial search coil magnetometers (160 Hz - 50 kHz). The position of the magnetometers and the unit under test is accurately determined with a laser system.
