The invention relates to a method and a device used for testing interference of electromagnetic radiation on a cable. The method is characterized by comprising steps that, a signal generator, a support, an antenna, a shielding chamber, a grounding board, a load set and leads are employed to establish the device for testing interference of electromagnetic radiation on the cable, the space electric field intensity around the cable is measured, electromagnetic simulation software is utilized to establish a cable coupling model, the relationship between the electric field intensity around the cable and an input voltage and current response coupled into a cable terminal load is extracted, and an input voltage and current response can be acquired through the relationship when an external electromagnetic environment is coupled with the cable terminal load. Through the method and the device, difficulties of small internal space and cable interference signal tests under the condition of dense cables can be effectively
