Abstract

The invention, which relates to the technical field of testing, proposes a calibration device for automotive electronic conduction interference-immunity testing. The calibration device comprises a signal generator, an amplification module, an inductive coupling clamp, a matching module, a measurement module, a transmission module and a tool fixture. The tool fixture is used for fixing a support transmission module and serving as a tool for connecting the transmission module with the matching module. An interference signal generation module injects the disturbance current into the inductive coupling clamp; and the induced current generated on the transmission line is verified by magnetic induction coupling. According to the calibration device, the testing reliability and stability are ensured; the operability and the repeatability are high; the device is operated simply with high economy. The device has advantages of simple and stable structure and saved time cost. In addition, the he invention also proposes a calibration method for automotive electronic conduction interference-immunity testing.

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...
