简单、准确、快速测量变频设备的特性

变频设备在通信、卫星和雷达系统中非常重要。罗德与施瓦茨矢量网络分析仪提供多种选件以测量这些组件的特性。R&S®ZNA 具备四个独立的相参信号源和两个内部本振,无需使用外部设备即可进行绝对相位混频器测量。R&S®SMARTerCAL 能够快速提供准确的校准结果。即使用户无法使用被测设备的本振,无论设备的内部本振漂移如何,嵌入式本振跟踪功能也可确保结果正确。

特性和优点

独特的硬件架构

快速设置,测量时间短

R&S® 四端口矢量网络分析仪具备四个内部相位相参信号源,是一款紧凑型测试系统,可用于任何变频测量。无需使用参考或辅助混频器,即可轻松执行混频器绝对相位测量。两个可选的内部本振信号源可提高变频损耗和群延时测量的测量速度,并降低迹线噪声。

嵌入式本振跟踪

测量真正的性能

嵌入式本振跟踪功能可测量和补偿被测设备的内部本振漂移效应,以提供准确的结果。本振跟踪功能确保在中频滤波器的最佳范围内进行测量,以提供真正的性能结果,而不受测量设备中频滤波器形状的影响。
