本文引用地址:http://butianyuan.cn/article/201612/333435.htm1.CTIA的OTA規(guī)范 (Testing Plan for Mobile Station Over the Air Performance v2.2);
2.3GPP/ETSI OTA antenna performance conformance testing 測試標(biāo)準 (TS 34.114);
3.中國信產(chǎn)部的YD 1484-2006-Ⅰ(移動臺空間射頻功率和接收機性能測量方法/Measurement Method for Radiated RF Power and Receiver Performance of Mobile Station)標(biāo)準;
4.無源天線測試(Passive antenna test)。
本系統(tǒng)采用的SG24的多探頭測量方案,是目前最先進的天線測量方法之一,有重復(fù)性高,準確度高,解析度高等優(yōu)點。是全球少數(shù)能完全符合CTIA要求的測試系統(tǒng)。能提供CTIA所需要的TRP/TIS測試。測試涵蓋:CTIA OTA(Cellular 850,PCS1900);天線3D場型測量、增益、天線效率、方向圖、極化性能。
