Wide range of Test and optimization of new devices and methods
with minimal effort
The performance and capabilities of radiocommunications
applications devices should be tested prior to purchase in order to
avoid unprofitable investments.
The R&S®GTA-RN5 puts radios through their paces to
verify their immunity to interference both in "clean" and in
crowded, realistic signal environments. For this purpose,
an interference signal or the signal from an external anten-
na is applied to the test scenario.
The system thus allows radio links and radios to be tested
for robustness with respect to unwanted as well as want-
ed interference (ECCM tests). Conversely, it is also pos-
sible to determine and optimize the settings that provide
the most effective jamming for dedicated radios and trans-
mission methods.
Typical tests

6Easy and Quick and flexible hardware configuration
The radios to be tested and, if necessary, a signal genera-
tor for supplying an interference signal, are connected via
reproducible setup their RF antenna outputs directly to the corresponding
connectors of the R&S®GTA-RN5. The radios can then be
operated as usual. Any further devices can also be tested
of scenarios simply by connecting them to the R&S®GTA-RN5 via the
RF cables. This makes it possible to examine a variety of
devices under identical test conditions.
Any connections required on the R&S®GTA-RN5 itself for a
specific application are made quickly and easily by means
of BNC cables. If the output signal level of connected
devices is too high, external attenuators can be inserted
between the devices and the R&S®GTA-RN5.

Rohde & Schwarz R&S®GTA-RN5 Radio Net Simulation Device 7Rapid setup of training scenarios using intuitive
control software
The graphical control software makes it possible to vary
the virtual positions of the connected devices in the ter-
rain without having to change their physical locations. All
defined radio stations can be displayed on a digital map by
means of the R&S®MapView geographic information soft-
ware. After any position change, the path losses are recal-
culated and activated in the device as required.
All parameters necessary for calculating the wave propa-
gation, e.g. the antenna height and the transmit power
of the radios, can be set in the operating software on
the control PC. From these parameters, the path losses
between the radios are calculated and set in the device.
The test and training scenarios created in this manner can
be saved and re-used as required.
