Description

technical field

[0001] The invention relates to an electromagnetic compatibility detection device, in particular to an electromagnetic detector for the electromagnetic compatibility diagnosis test inside a vehicle. Background technique

[0002] Electromagnetic waves are present all the time in daily life. From the perspective of physics, electromagnetic waves are a form of motion of the electromagnetic field. Electricity can generate magnetism, and magnetism can also bring electricity. The changing electric field and changing magnetic field constitute the An inseparable unified field is the electromagnetic field, and the propagation of the changing electromagnetic field in space forms electromagnetic waves. Although different forms of electromagnetic waves have the same essence, their wavelengths and frequencies are very different, which brings certain difficulties to the suppression and prevention of electromagnetic interference. Electromagnetic compatibility (EMC) refers ...
