Description

technical field [0001] The invention relates to the technical field of testing, more specifically, to a calibration device and a calibration method for automotive electronic conduction immunity testing. Background technique [0002] The various wiring harnesses connected to the car become a passive receiving antenna network during the operation of the electronic equipment, and it is very easy to generate induced voltage or current under the action of the external electromagnetic field. A large part of the electromagnetic field in the space is magnetically coupled through the bundled cable harness. , causing interference to on-board electronic components / modules. The purpose of the conduction immunity test is to verify whether the automotive electronic components / modules can work normally to achieve their expected performance state or perform their expected design functions when they are interfered by the radio frequency electromagnetic energy coupled by the cable harness, an...
