Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a highly reliable induction peak signal generating device and system. Background technique [0002] Foreign countries have carried out many years of research on the electromagnetic compatibility of aviation airborne equipment, and established corresponding institutions. Among them, RTCA is a non-profit organization established for the public interest to promote the development of aviation technology and avionics systems. The agency serves on federal advisory committees and develops coherent solutions to the problems facing modern aviation. In 2004, 2007, and 2010, RCTA successively formulated the specifications for EMC testing of aviation airborne equipment, namely DO160E, F, and G. The DO160 standard specifies a series of minimum standard environmental test condition classifications and applicable test procedures for airborne equipment. The purpose of this test...

AI Technical Summary

Problems solved by technology

[0004] 1. The peak amplitude of the induced voltage generated by the existing scheme is unstable;

[0005] 2. The technology of the existing scheme is immature. Since the upper limit of the mechanical on-off frequency of the relay cannot reach 10Hz, the peak group frequency generated by the "vacuum relay" cannot meet the upper limit of the standard requirement.
