EIRP值是RDSS用户机的一个重要性能指标。利用RDSS闭环测试系统测量北斗RDSS用户机EIRP值的主要不确定度来源包括RDSS模拟器功率测量重复性、模拟器功率测量偏差、空间损耗和接收天线增益修正不准等。利用标准增益喇叭天线、标准峰值功率计和矢量网络分析仪组成校准系统，对RDSS闭环测试系统进行校准，可以有效提高RDSS闭环测试系统EIRP值的测量值准确度。利用该方法进行校准后，RDSS闭环测试系统EIRP值的测量不确定度可以达到1.5dB以下，满足北斗RDSS用户机测试需求。
EIRP is an important performance index of RDSS user receiver. The major uncertainty source of Beidou RDSS user receiver EIRP measurement using RDSS closedloop test system includes power measurement reproducibility and power measurementdeviation of RDSS simulator, inaccuracyof space loss and antenna gain correction.It can effectively improve the accuracy of EIRP testing by using the calibration system consists of a standard gain horn antenna, a standard peak power meter and a Vector network analyzer. After calibrating, the uncertainty of testing EIRP is less than 1.5dB, meets the testing requirements.
