Comparison of susceptibility measurements on a reference test setup in two reverberation chambers including cabling variations

By using our own reference test setup based on a Raspberry Pi single board computer, we intend to elucidate differences between high power electromagnetics test environments and labs. Having a reliably reacting test setup enables us to shed light on measurement uncertainties as well as intricacies of setting up a device under test. We do show a direct comparison of measured susceptibility profiles of the setup in two different reverberation chambers, yielding good alignment of results. This is complemented by investigating a series of cabling variations slightly impacting the coupling behavior of our system. Results from shortening inner cabling or folding down a right angle bent point to a slightly lower susceptibility.
