当前,各种3G基站系统的快速发展对WCDMA射频部分、码域部分维护性能稳定提出了更高的要求,UMTS基站系统的维护测量日益要求测量人员进行频域、时域、幅度域、调制域等全方位的性能评估,此时能够提供多种域分析能力的测试设备愈发显示出其重要性。WCDMAUMTSNodeB发射机的特征描
At present, the rapid development of various 3G base station systems places higher requirements on the WCDMA RF part and the maintenance performance of the code part. The maintenance and measurement of the UMTS base station system increasingly require the measurement personnel to perform frequency domain, time domain, amplitude domain, modulation domain Such as a full range of performance evaluation, at this time to provide a variety of domain analysis capabilities of test equipment increasingly shows its importance.
