Abstract

The invention relates to a full electric wave darkroom possessing both aerial radio frequency testing and EMC testing abilities, belonging to the technical field of aerial radio frequency testing darkroom and full electric wave darkroom design for radio equipment. And it comprises shielding casing, wave absorption material layer bonded with inner wall of the casing, false wall, darkroom door, turntable and tested equipment supporting device installed in the casing, antenna bracket system, vent illuminating device, filter, safe and electrical device and interface board to be connected with a tester, where the shielding casing is L-shaped, on two sides of the L shape are OTA testing darkroom and full electric wave darkroom, mutually vertical and interconnected, and a set of turntable and tested equipment supporting device is arranged at the junction of the two darkrooms. And it can reduce darkroom construction cost and raise utilization ratio.

Description

technical field [0001] The invention belongs to the technical field of air radio frequency test anechoic chamber and all-wave anechoic chamber design of radio equipment. Background technique [0002] There are many types of shielded anechoic chambers, such as full anechoic chambers, semi-anechoic chambers, and other types of anechoic chambers designed to meet test requirements. Although the test items in different anechoic chambers are different, they generally include the shell shielding shell, the inner wall of the shell combined with a layer of absorbing material, the false wall, the anechoic chamber door, the turntable of the equipment under test installed in the anechoic chamber and its supporting device, and the antenna bracket Systems, ventilation and lighting, filters, grounding, safety and electrical installations, measuring instruments and interface boards for connection to measuring instruments. Electromagnetic compatibility test items such as radiation spurious ...
