Abstract:

Aiming at the technical requirements for simultaneous test and assessment of equipment at both ends, the research on the two-wire system double-probe bulk current injection equivalent replacement radiation test method is carried out. Taking the nonlinear response system as the tested device, the analysis and calculation model of the response of the tested device under the two conditions of radiation method and injection method is established. The equivalent corresponding relationship is deduced between the injection excitation source voltage and the radiation field intensity, and the conditions and methods for the double-probe bulk current injection equivalent high field electromagnetic radiation test are proposed, and the test verification is carried out. The test verification results show that the method of double-probe bulk current injection equivalent high field electromagnetic radiation test can eliminate the influence of the impedance parameters of the two terminals of the two-wire system. And the method can make the response of the two ends consistent under the conditions of radiation and injection at the same time, which can achieve accuracy.

Key words: two probes, bulk current injection, two-wire system, electromagnetic radiation, nonlinear system, equivalent substitution
