Rohde & Schwarz R&S®EB500 Monitoring Receiver 5
Reliable detection of radio interference caused, for
example, by defective electronic equipment
To master these tasks, the receiver includes special func­
tions such as selectable measurement time and continu­
ous or periodic level output. Since these functions are
also effective in the panorama scan spectrum, even non­
periodic interferers can be easily detected. Such interferers
are otherwise very difficult to detect due to their irregular
appearance in a quickly changing spectrum.
Fast and effective identification of interference
sources, e.g. at airports
The simultaneous use of the R&S®GX430 analysis software
allows efficient differentiation between wanted signals and
possible interference signals. Fast differentiation is espe­
cially important in security­critical radio scenarios (e.g. air
traffic control, ATC) as it prevents high failure costs for the
service provider. The combination of a fast panorama scan
to acquire an overview of the situation with subsequent
scanning and analysis in fixed­frequency mode based on
I/Q data is particularly well suited to such applications.
In the panorama scan mode, the frequency range of
interest is scanned in steps of max. 20 MHz, and an FFT of
suitable width is calculated for each step. The step width
for the fast panorama scan can be selected to match the
channel spacing used by a wide variety of radio services.
The panorama scan provides high scan rates at narrow
resolution bandwidths, yielding high sensitivity and signal
resolution.

professional radio
networks
Interference in radiocommunications, e.g. at airports, not only impedes operation – it may even pose a threat to
life.
Its high performance and wide range of special
functions make the R&S®EB500 an ideal choice for
detecting all types of radio interference efficiently.
