Abstract

The invention is suitable for the technical field of detection equipment, and provides a filter testing device which comprises a shielding main body, a product positioning seat, a high-frequency testing plate and a connecting assembly. The high-frequency test board is connected with an external test circuit or a test device, a product can be placed in the positioning groove when the product is tested, at the moment, the detection end of the product is connected with the high-frequency test board through the connecting assembly, and meanwhile grounding connection of the product is achieved through the grounding part. Compared with a testing device in the prior art, the product can be connected with a testing circuit or testing equipment by placing the product in the positioning groove in the product positioning seat, so that the product can be tested more quickly and conveniently, and the structure is small, exquisite and simple. And meanwhile, the product positioning seat, the high-frequency test board and the product in the test process are all arranged in the shielding groove, so that external electromagnetic radiation can be shielded, the influence of the external electromagnetic radiation on a test result is avoided, and the test result is more accurate.
