Anritsu ME453L 微波系统分析仪
MICROWAVE SYSTEM ANALYZER TRANSMITTER and RECEIVER
厂家: 日本安立
性能指标pdf
ME453系列产品是用来测量陆地微波中继系统和卫星通讯系统BB和IF频段传送线特性的仪器。它们可以对上述的传输畸变进行测量和分析。产品在设计上特别考虑了测量类别、精度、性能、功能、尺寸等因素。因此，它可以应用于所有微波无线中继系统如：FDM-FM中继系统、高效大容量数字微波无线中继系统、INTELSAT和其它卫星通讯系统。多路传输电话、电视、PCM和数据通讯信号通常都通过微波无线中继系统传送。然而，当线路中有线性畸变（幅度畸变、相位畸变）或非线性畸变（对模拟信号影响严重）存在时，将会在电话传送中出现畸变噪音；在电视传送中丢失清晰度和色彩一致性；在数字传送中产生代码干扰。
特点：
·自动接收设置和显示
·信号对噪音平均

The Anritsu ME4553L is used to measure the transmission line characteristics in the BB and IF bands in terrestrial microwave radio relay systems and in satellite communication systems. The distortion of these transmissions can be measured and analyzed with the ME453L. The ME453L Microwave System Analyzer can also be used to measure FDM-FM links and digital microwave communication links. The ME453L is useful in link device adjustment, construction, maintenance, and research and development applications.
