The test system includes a measurement system, a control system, a pulse high voltage source and a bounded waveguide transmission line connected in sequence, and the pulse high voltage source is set to two; The establishment method of the test system is as follows: step one: according to the long pulse and short pulse in the theoretical electromagnetic pulse radiation field, respectively determine the technical parameters of the transient electromagnetic field; step two: according to the technical parameters, carry out the bounded waveguide transmission line and two The parameter setting of two pulsed high voltage sources; Step 3: described two pulsed high voltage sources are respectively connected with the bounded waveguide transmission line; Step 4: verify whether the technical parameter deviation of actual electromagnetic pulse radiation field meets the design standard, the present invention can improve The service life and environmental adaptability of the tested equipment, cost saving, high design accuracy, great practical reference value of system parameters, flexible configuration of various experimental environments, and strong practicability.

Description

technical field [0001] The invention relates to the technical field of laser equipment, in particular to a method for establishing an electromagnetic immunity test system. Background technique [0002] The interaction of electric field and magnetic field produces electromagnetic waves, and the phenomenon that electromagnetic waves are emitted or leaked into the air is called electromagnetic radiation. Electromagnetic radiation is an invisible and intangible substance that exists in a special form. Electrical equipment works in the case of transient strong discharge, and is susceptible to electromagnetic interference during operation. In particular, during the pulse generation process, it will be subject to serious electromagnetic interference, which will affect the sampling, feedback, triggering and other signal control operations of the equipment, reducing the The technical performance index of the equipment. [0003] "Electromagnetic pollution" has become the fifth large...
