带下变频器的便携式天线

R&S®HE400DC 手持式定向天线配备下变频器,可将 R&S®PR200 便携式监测接收机的频率范围从 8 GHz 扩展至 20 GHz。天线和 R&S®PR200 可用于定位发射机和干扰源。操作人员可以手动将天线指向信号强度最大的方向,从而查找方向。
天线包括天线手柄、定制的接收机电缆组件和可通过锁定环轻松连接的不同天线模块。天线具有六个不同的天线模块,可用于接收垂直或水平极化信号。

特性和优点

清晰的定向方向图

提供明确的测量结果  

适用于 R&S®HE400DC 的定向天线模块具有清晰的定向方向图,因此可以确保天线指向信号源,从而清楚测定方向。
在反射环境中,需要在不同位置进行多次测量。

宽动态范围

得益于可切换的有源和无源模式(LNA 开关)  

用户可以激活内置的低噪声放大器 (LNA) 以提高系统灵敏度。在无源模式下,用户可以设置放大器旁路,也可以在强力发射机附近使用天线。

体积小,支交宽广的频率范围

易于操作  

R&S®HE400DC 具有模块化特性和不同的天线模块,是一款非常紧凑的解决方案。
操作人员可以使用便携式系统覆盖 20 MHz 至 20 GHz 的宽频率范围。

自动检测天线模块/极化

保证操作安心无忧  

R&S®HE400DC 可以检测连接的天线模块及其极化。相关数据被发送至连接的 R&S®PR200 便携式监测接收机。接收机使用此数据自动选择正确的天线系数表。操作人员不必进行手动更改, 因此不会由于使用错误的天线系数表而导致测量结果有误。

触发按钮可用于外部接收机

便于启动测量  

R&S®HE400DC 微波手持式定向天线具备一个用于启动测量的触发按钮。连接的 R&S®PR200 便携式监测接收机会执行测量并存储结果。用户无需操作接收机,即可立即开始测量信号。

消除操作疲劳

采用精密的天线设计和材料,尽可能减轻重量  

R&S®HE400DC 微波手持式定向天线重量轻,易于操作。它甚至配备一个舒适扶手,可以尽量减轻操作人员在进行长时间测量时产生的疲劳。

包含 GNSS 接收机和电子罗盘

提供更多有用信息  

处理相关信号时,需要知道信号强度、传输时间以及发射和接收位置的方向。R&S®HE400DC 使用 GNSS 数据提供操作人员的位置信息,并通过电子罗盘数据提供天线的方向信息。这些信息被传输至接收机,可以与测量的信号数据一起存储。
