Considerations for performing reverberation chamber immunity testing with frequency stirring

In this work we address some considerations for using frequency sweeping for immunity tests in reverberation chambers and compare these with tuner sweeping. Previous investigations have discussed the impacts of frequency scanning rate on immunity testing and several authors have identified that susceptibility bandwidth of the equipment under test is a significant factor for immunity testing but have not quantified its effects. We show the interaction of the reverberation chamber quality factor bandwidth and the susceptibility bandwidth of the equipment under test is critical while planning a frequency stirring immunity test and identify some issues for frequency stirring for immunity tests.
