安立Anritsu MT8872A通用无线测试仪操作流程
Published on2026-04-20
安立Anritsu MT8872A是款面向5G、Wi-Fi 6E等多制式无线通信设备的高性能量产测试设备，支持双通道并行测试与12端口同步连接，适用于智能手机、物联网终端及通信模块的大规模生产线，以下就是Anritsu MT8872A的操作流程。Anritsu MT8872A操作流程1.设备准备与连接将MT8872A主机通电并启动，确认安装了所需的TRX测试模块（如MU887002A，支持12天线端口）。使用射频线缆将被测设备（DUT）的天线端口与测试模块端口直连，建议采用低损耗线缆以减少连接误差。若进行双设备并行测试，可在主机内安装两个测试单元，分别连接两台DUT。2.配置测试参数登录设备本地界面或通过PC控制软件（如Anritsu提供的工具）调用预设模板。选择对应无线标准：如5G NR Sub-6 GHz、Wi-Fi 6E（802.11ax）、Bluetooth等。加载测试项目，例如EIRP（有效全向辐射功率）、OBW（占用带宽）、调制精度（EVM）等关键指标测试项。3.执行非信令测试（Non-Signaling Mode）MT8872A支持高效的非信令模式测量，无需建立完整通信链路，适合高速量产环境。启动自动测试序列，系统将完成信号发射与接收性能的快速验证，包括多天线MIMO配置识别和160MHz带宽信号解析。4.结果分析与报告输出测试完成后，设备自动生成符合Wi-Fi联盟或3GPP规范的认证格式报告。可通过USB、LAN接口导出数据，用于质量追溯或产线优化。5.高频段测试注意事项（如6GHz频段）建议在屏蔽环境（>30dB衰减）中进行测试，避免外部干扰引入±1.5dB测量误差。可启用动态噪声补偿算法，将精度提升至±0.5dB。
