Test system for electronic device false triggering under strong electromagnetic radiation by applying optical fiber communication

Abstract

The invention discloses a test system for electronic device false triggering under strong electromagnetic radiation by applying optical fiber communication, which comprises a radio frequency signal generator, a power amplifier, a GTEM cell, an electric-optical signal converter, a field strength tester, an optical fiber, an optical-electric signal converter and an oscilloscope, wherein the radio frequency signal generator generates radio frequency electric signals; the power amplifier amplifies the radio frequency signals; the GTEM cell uses the amplified radio frequency signals to excite a uniform high-frequency strong electric field around a core board; the electric-optical signal converter is used for converting false triggering electric signals generated by a tested electronic device due to radiation interference to optical signals not disturbed by the radiation interference; the optical signals are transmitted to the optical-electric converter outside the cell through the optical fiber and are converted to electric signals; and finally, the false triggering electric signals are displayed by the oscilloscope. Complete transmission of the electric signals with no interference in the strong electromagnetic radiation environment can be realized, and the system has the advantages of shielding outer interference and isolating pollution on the outside by the self electromagnetic field.
