Abstract

An electromagnetic detector for diagnostic - testing compatibility of vehicle internal electromagnetism has electric field probe and magnetic field probe as the two are connected to low noise amplifier respectively through adapter. The detector can be used to diagnose leakage of shielding shell and various components on electronic circuits as well as radiating emission of similar electromagnetic disturbance source, and can be connected to computer through EMI detection receiver.

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 ...
