Testing of the antenna-feeder path of mobile base stations (RBS)

According to ROHDE&SCHWARZ customers, the FSH3 portable spectrum analyzer is an indispensable tool for deployment and maintenance of mobile base stations.

A wide selection of basic and additional functions aimed at facilitating the engineer's work will allow to reduce time and, accordingly, costs. Among the most useful functions, we note the following: obtaining a spectrogram in the selected frequency range, measuring the distance to damage in the cable (DTF), measuring the reflected signal, power (in the channel, TDMA, CDMA), measuring the bandwidth, etc.

The analyzer has a high-contrast color display of 320x240 pixels and can work up to 4 hours from the built-in battery. The ease and convenience of setting measurement parameters is not difficult to master the analyzer. Parameters can be set directly by manipulating the controls on the front panel of the FSH3, as well as through the free FSH View software package. After carrying out all the necessary measurements, you can easily make a report on the work done using the spectrograms stored in the analyzer (up to 100 curves). They can be easily transferred both in the form of pictures and data to your computer. It should be noted that the PC is connected to the spectrum analyzer using a cable with an optical connection (transformation of an electrical signal from the RS232 port into a light signal), which will ensure that there is no influence of additional electrical magnetic fields on the analyzer circuit.

In the "Useful links" section, you can find the document "Testing Mobile Radio Antenna System with FSH", which allows you to master the principles and methods of measuring various parameters of mobile communication base stations.
