Speed up your EMC measurements: Closed-loop e-field control in reverberation chambers

23 Oct 2025
Thursday, October 23, morning session
EMC measurements can take a long time. This presentation will show a way speed up the measurement and save time and money. It will start with a brief introduction on the basics of reverberation chambers (RCs), discussing validation and radiated immunity testing. The stage will show a small but fully working, stirred RC. Eight fast, synchronized electric-field probes will showcase real-time e-field strength measurements and closed loop e-field control based on statistics. Lumiloop's LSProbe e-field probes enable accelerated measurements according to ISO 11451-5. The RC basics will also be visualized using live measurements, helping attendeed quickly grasp how the invisible electric field behaves.
  • Automotive EMC radiated immunity measurements can be done in a reverberation chamber, according to ISO 11451-5
  • A reverberation chamber is much cheaper to build and operate than a traditional absorber chamber
  • Electric field strength and its distribution inside a reverberation chamber changes rapidly with DUT loading, frequency, stirrer position and more
  • Lumiloop's super-fast, hardware-synchronized LSProbe electric-field probes read field strength distribution in real time
  • Lumiloop's built-in real-time statistics evaluation enables closed-loop e-field control, to compensate for all unwanted factors
