RF testing apparatus, movable testing device thereof, and case module thereof

A movable testing device of an RF testing apparatus, comprising:

• a case module having an accommodating space arranged inside thereof, a cable hole, and a front entrance, wherein the cable hole and the front entrance are in spatial-communication with the accommodating space, the case module includes at least two electromagnetic shielding units respectively covering the cable hole and the front entrance, and each of the at least two electromagnetic shielding units includes:
• a stepped structure including a plurality of annular treads and a plurality of annular risers staggeredly arranged with the annular treads;
• a cover detachably fastened to the stepped structure and including a plurality of abutting treads and a plurality of abutting risers staggeredly arranged with the abutting treads, wherein the abutting treads respectively face and are spaced apart from the annular treads, and the abutting risers respectively face and are spaced apart from the annular risers;
• and
• a shielding structure including a plurality of first isolation members and a plurality of second isolation members staggeredly arranged with the first isolation members, wherein each of the abutting treads and the corresponding annular tread facing each other are configured to sandwich one of the first isolation members, and contacting regions of each of the first isolation members with respect to the corresponding abutting tread and the corresponding annular tread each have a closed annular shape, and wherein each of the abutting risers and the corresponding annular riser facing each other are configured to sandwich one of the second isolation members,
• wherein the stepped structures of the at least two electromagnetic shielding units are respectively arranged around the cable hole and the front entrance;
• an RF analytical instrument detachably arranged in the accommodating space of the case module by passing through the front entrance;
• a testing socket disposed on a top portion of the case module and exposed from the case module for providing an insertion and an electrical connection to a device under test (DUT) to be tested;
• and
• a plurality of internal transmitting cables arranged in the accommodating space, wherein at least one of the internal transmitting cables has two opposite ends respectively connected to the testing socket and the RF analytical instrument.

An RF testing apparatus, comprising:

• an automatic testing platform having a testing space and an insert hole in spatial-communication with the testing space;
• and
• a movable testing device including:
• a case module having an accommodating space arranged inside thereof, a cable hole, and a front entrance, wherein the cable hole and the front entrance are in spatial-communication with the accommodating space, the case module includes at least two electromagnetic shielding units respectively covering the cable hole and the front entrance, and each of the at least two electromagnetic shielding units includes:
• a stepped structure including a plurality of annular treads and a plurality of annular risers staggeredly arranged with the annular treads;
• a cover detachably fastened to the stepped structure and including a plurality of abutting treads and a plurality of abutting risers staggeredly arranged with the abutting treads, wherein the abutting treads respectively face and are spaced apart from the annular treads, and the abutting risers respectively face and are spaced apart from the annular risers;
• and
