Abstract: A case module of a radiofrequency testing apparatus has a cable hole and a front entrance, and includes two electromagnetic shielding units respectively covering the cable hole and the front entrance. Each electromagnetic shielding unit includes a stepped structure, a cover detachably fastened to the stepped structure, a shielding structure sandwiched between the stepped structure and the cover. The stepped structures of the two electromagnetic shielding units are respectively arranged around the cable hole and the front entrance. Each of the stepped structure and the cover includes a plurality of treads and a plurality of risers staggeredly arranged with the treads, and the treads and the risers of the stepped structure respectively face those of the cover. Any two faced treads are configured to sandwich a part of the shielding structure, and any two faced risers are configured to sandwich the other part of the shielding structure.

Abstract: A movable testing device includes a case module, an aligning box, a lift mechanism connecting the case module and the aligning box, and a flexible shielding member having a tubular shape. The case module has a first accommodating space and a first opening formed on a top portion thereof. The aligning box has a second accommodating space and a second opening formed on a bottom portion thereof. The lift mechanism is configured to rise or fall the aligning box with respect to the case module. The flexible shielding member has a first end portion and an opposite second end portion, which are respectively and seamlessly fastened to the case module and the aligning box and are respectively arranged around the first opening and the second opening. The flexible shielding member defines an adjustable channel in air-communication with the first accommodating space and the second accommodating space.
