Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic compatibility detection, in particular to an electromagnetic compatibility detection device for integrated circuit products. Background Art

[0002] An electromagnetic compatibility (EMC) testing device is a test device specifically designed to analyze and evaluate whether electronic equipment or systems can operate normally in an electromagnetic environment and will not generate unacceptable electromagnetic interference to other devices. It mainly includes two tests: the electromagnetic interference (EMI) generated by the equipment and the immunity to external electromagnetic interference (EMS). Currently, most existing EMC testing devices expose products to the outside during the testing process and lack effective shielding and clamping. In an unshielded environment, if the external electromagnetic interference is severe, the measured electromagnetic interference level will include not only the interference generated by the device under test, but also interference from other interference sources in the environment, which may affect the accuracy of the test results.
