Problems solved by technology

[0007] That is to say, in the existing test room, the tester will change the test antenna during the test to perform EMC test or RF test. However, the sensitivity of RF test is quite high, and even a little movement will have a considerable impact on the test results. discrepancy, so the test results obtained are easily questionable about their accuracy

Abstract

A kind of testing room of double testing antenna is used to test electromagnetic wave of electronic device; it mainly possesses an antenna rack which a testing antenna can be mounted selectively, so the two relative tests of electromagnetic wave can share a testing room, and test error induced by moving testing antenna can be decreased.

Description

【Technical field】 [0001] The invention relates to a testing room for electromagnetic wave related testing, especially a testing room with double testing antennas. 【Background technique】 [0002] With the advancement of technology, all kinds of computer (Computer), communication (Communication) and consumer electronics (Customer Electronic) integrated system equipment are developing rapidly to bring people more convenient life. However, with the widespread use of related products of electronic and electrical equipment, a relatively complex electromagnetic noise environment is created. [0003] Therefore, all related products of electronic and electrical equipment must comply with relevant electromagnetic compatibility (Electromagnetic Compatibility; EMC) standards and specifications before they can be sold. Electromagnetic compatibility testing is divided into electromagnetic interference and electromagnetic tolerance testing. Therefore, during the entire product development...
