1 概述R&S DDF1555便携式测向机配备专门适用于室外操作的紧凑型机壳,可同时实现精确测向与宽带监测能力。若再配备R&S紧凑型测向天线,便形成了R&S DDF1555这一既机动便携又可以在室外环境中作业的解决方案(见图1)。R&S DDF1555测向系统依靠R&S专利的高精度测向方法,既可作为便携式的移动测向系统来使用,也可配置为可搬移式测向站。由于重量轻、尺寸紧凑,R&S DDF1555系统可快速便捷地搭建和配置。另外,低功耗设计使其可使用电池长时间供电进行工作。测向机内集成了宽带接收机的全部功能,包括宽频范围的快速全景扫描(PSCAN),以及瀑布图显示,便于显示信号。
1 Overview The R & S DDF1555 Portable Direction Finder is equipped with a compact enclosure designed for outdoor operation for accurate direction finding and broadband monitoring. With the R & S Compact Direction Finder antenna, the R & S DDF1555, a mobile and portable solution that works outdoors (see Figure 1), is formed. The R & S DDF1555 direction finding system relies on R & S’s patented high-precision direction finding method, either as a portable mobile direction finding system or as a portable direction finding station. Due to its light weight and compact size, the R & S DDF1555 system can be quickly and easily set up and configured. In addition, the low-power design allows it to operate on batteries for long periods of time. The DFM incorporates all the features of a wideband receiver, including wide-area fast panning (PSCAN) and waterfall display for easy signal display.
