What kind of testing does the Electromagnetic Compatibility and Magneto-static Laboratory do?
In the EMC lab the following kind of measurements /tests can be carried out:
- All kinds of electric measurements (voltage, current, bonding, insulation)
- RF measurements (spectrum, impedance, power)
- EMC tests and measurements (radiated and conducted, continuous wave and transient)
Emission measurements are aimed to characterise the electromagnetic noise emitted by the equipment under test and compare versus project specific emission limits.
During susceptibility tests the equipment under test is exposed to defined electromagnetic disturbances and it is checked whether the equipment is still functioning as expected and its performance is not degraded.
In the Magneto-static lab the following measurements are carried out:
- DC magnetic field measurements (magnetic characterisation)
- Magnetising and demagnetising (perm/deperm) of parts and units
With the MCF the earth magnetic field can be compensated in a test volume and the DC (and low AC) magnetic field from the unit under test can be measured using sensitive magnetometers. This is performed in three axis and rotating the unit under test by 360 degrees. Thus the magnetic properties of the unit under test can be characterised and a representative dipole model is derived from the measurements. The magnetic coils system can also be used to induce fields on the unit under test or to magnetise / demagnetise it in order to ensure defined magnetic conditions w.r.t. the magnetic hysteresis of the material.
