本测试系统支持规范:
1.CTIA的OTA规范 (Testing Plan for Mobile Station Over the Air Performance v2.2);
2.3GPP/ETSI OTA antenna performance conformance testing 测试标准 (TS 34.114);
3.中国信产部的YD 1484-2006-Ⅰ(移动台空间射频功率和接收机性能测量方法/Measurement Method for Radiated RF Power and Receiver Performance of Mobile Station)标准;
4.无源天线测试(Passive antenna test)。
本系统采用的SG24的多探头测量方案,是目前最先进的天线测量方法之一,有重复性高,准确度高,解析度高等优点。是全球少数能完全符合CTIA要求的测试系统。能提供CTIA所需要的TRP/TIS测试。测试涵盖:CTIA OTA(Cellular 850,PCS1900);天线3D场型测量、增益、天线效率、方向图、极化性能。
