Abstract

The invention discloses an electromagnetic pulse interference test system and method. The system comprises a transmission line pulse test device, a to-be-tested digital circuit and an auxiliary monitoring device. The digital circuit is provided with at least one to-be-tested port, at least one state port and an output port corresponding to each to-be-tested port, wherein the to-be-tested port andthe state port are specified in advance, And the at least one state port represents the working state of the digital circuit; the transmission line pulse test equipment is used for injecting an electromagnetic pulse into each to-be-tested port and monitoring the leakage current of the output port corresponding to the to-be-tested port; the auxiliary monitoring device comprises a plurality of auxiliary monitoring units; each state port is correspondingly connected with one of the plurality of auxiliary monitoring units; and each auxiliary monitoring unit connected with a state port is used formonitoring signals of the connected state port in real time. According to the invention, the test efficiency of electromagnetic pulse interference test can be improved.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic pulse interference testing, and in particular relates to an electromagnetic pulse interference testing system and method. Background technique [0002] With the development of pulse power amplification technology, radar antenna technology and pulse weapon technology, the electromagnetic environment is becoming more and more complex, and digital circuits are more and more susceptible to electromagnetic pulse interference; when electromagnetic pulses are coupled into digital circuits, instantaneous High-amplitude voltage and / or current; when the generated voltage and / or current exceeds the capacity of the circuit, it will cause damage or even damage to the digital circuit. Therefore, it is necessary to conduct electromagnetic pulse interference tests on digital circuits to understand the immunity of digital circuits to electromagnetic pulses. When testing, it is necessary to input electroma...
