Background McCollum and Clark[1] proposed a new test method to replace or supplement low frequency radiated emissions testing in frequency bands where intentional receivers are not utilized. The new method, referred to as bulk current emissions testing, is complimentary to the bulk current injection or Cs114, testing of MIL-STD-461D12]. McCollum and Clark identified forward work required to understand the cable coupling process and how to apply the limit and test method. The previous work was based on coupling between shielded cables; cables with low common mode loop impedance. Cable coupling factors for high loop impedance and mis-matched loop impedance are presented herein
