Radiofrequency testing apparatus and movable testing device

A radiofrequency (RF) testing apparatus, comprising:

• an automatically testing platform having a testing space and an inserting hole in air-communication with the testing space;
• and
• a movable testing device including:
• a case module having a first accommodating space in an interior thereof, wherein a top portion of the case module has a first opening in air-communication with the first accommodating space;
• an aligning box having a second accommodating space in an interior thereof, wherein a bottom portion of the case module has a second opening in air-communication with the second accommodating space;
• a lift mechanism connecting the case module and the aligning box, wherein the lift mechanism is configured to rise or fall the aligning box with respect to the case module;
• an electromagnetic shielding cloth formed as a tubular structure having a first end portion and an opposite second end portion, wherein the first end portion of the electromagnetic shielding cloth is seamlessly fastened to the case module and is arranged around the first opening, the second end portion of the electromagnetic shielding cloth is seamlessly fastened to the aligning box and is arranged around the second opening, and an inner space of the electromagnetic shielding cloth is defined as an adjustable channel in air-communication with the first accommodating space and the second accommodating space, wherein the cooperation between the electromagnetic shielding cloth and the case module and the cooperation between the electromagnetic shielding cloth and the aligning box are configured to block an external electromagnetic signal to enter into the first accommodating space and the second accommodating space through the first opening and the second opening,
• wherein when the movable testing device is moved toward the automatically testing platform to arrange the aligning box under the inserting hole, the lift mechanism is configured to move the aligning box to enter into the testing space through the inserting hole.
