Abstract

Embodiments of the present invention provide a cable electromagnetic radiation analysis method and system, which belong to the field of electromagnetic radiation testing. The specific method includes performing a radiation interference test on a device under test including several cables with a set test frequency range; determining the frequency point where the radiation does not meet the limit requirements; generating a test wave signal with the same frequency as the frequency point, and After the test wave signal is amplified, it is connected to the cables one by one, and each cable is used as an electromagnetic wave radiation antenna; the electromagnetic radiation signal of each cable is tested, and compared with the frequency point where the radiation does not meet the limit value requirements. Yes, identify the cable that caused the device test results to exceed the limits. The method of the embodiment of the present invention can quickly check the cables inside each device, and does not need to repeatedly use the electromagnetic radiation test darkroom to repeat the test over and over again, improving the efficiency by 80%. The test time and test cost are saved to the greatest extent.

Description

technical field [0001] The invention relates to the field of electromagnetic radiation testing, in particular to the analysis of cable electromagnetic radiation problems. Background technique [0002] Electromagnetic waves move in the form of waves in space by electric fields and magnetic fields that oscillate in phase and are perpendicular to each other. The propagation direction of electromagnetic waves is perpendicular to the electric field. The speed of electromagnetic waves in vacuum is fixed, and the speed is the speed of light. An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Radiation interference means that the interference signal generated by electronic equipment transmits the interference signal to another electrical network or electronic e...
