Flexible operating concept
The R&S®UMS200 offers two control methods. In the basic configuration, the operating system (Windows XP Embedded) and all equipment interfaces are publicly available and documented. End customers and system integrators can develop their own software applications for customer-specific requirements. Rohde & Schwarz also provides optional monitoring software.
Flexible remote control
The R&S®UMS200 was designed as an unattended, remote controlled radiomonitoring and DF system. The system comes with a LAN interface for remote control. High data transfer rates help ensure that all measured data (i.e. measurement values, bearings, audio data, IF spectra, I/Q data) is transferred without loss to the monitoring control center, where it can be analyzed and processed.
Ready for local operation
Users have the option of controlling the R&S®UMS200 remotely via 2G/3G mobile radio networks. The system can be factory-equipped with modules for GSM/UMTS and CDMA/CDMA2000®. 2G networks (GSM, CDMA) in particular have significantly lower transmission rates. The intelligent control mechanisms in the Rohde & Schwarz monitoring software make optimum use of the network bandwidth. Compression algorithms, for example, reduce the data volume in audio signals and help ensure that the monitoring control center receives the audio data needed for analysis and identification.
The R&S®UMS200 has connections for a keyboard, mouse and monitor. After the protective plate has been removed, the R&S®UMS200 is ready for use in a fixed monitoring station or a vehicle. The changeover to local operation is fast and easy, an important prerequisite for integration in vehicles.
Standalone solution and large network
Even a single R&S®UMS200 is an extremely high-performance monitoring station, both in local operation as a standalone solution or as an unattended remote-controlled station. The system's strengths become clear when it is networked with other stations: In a network with other direction finders, cross-bearing fixes and triangulation can be performed to determine the precise location of a transmitter.
Four antenna inputs
To use the R&S®UMS200 in Rohde & Schwarz monitoring networks, the user only needs to update the system configuration. The R&S®UMS200 can also be integrated in other networks via its open interfaces.
Four antenna inputs are available for all tasks, frequencies and polarizations. Depending on the configuration (number of receivers and the presence of the direction finder), various switching options are implemented.
Extremely high frequency accuracy
The optional R&S®UMS12-H6 DC feed allows the use of active antennas. The antennas receive their power directly from the R&S®UMS200.
The optional R&S®UMS20-B3 frequency reference delivers an extremely accurate time and frequency reference. The 10 MHz reference signal has an accuracy of up to 5 × 10–12 (GPS synchronized, 24 h average).
The size of the R&S®UMS200 has been kept to an absolute minimum by systematically using modules and components instead of entire instruments. As a result, the system is so compact that it can be installed on the mast right next to the antennas. It is easy to find an installation location because a separate building or shelter is not necessary.
Flexible power supply
The modular design also minimizes power consumption, which reduces operating costs.
The system can be supplied with power both from an AC network (100 V to 240 V AC) and a DC supply (10 V to 30 V DC).
Prepared for all environments
It can be simultaneously fed with AC and DC power. AC power has priority. In the case of an AC power failure, the system automatically switches over to the DC power supply – with no interruption in operation.
The R&S®UMS200 was specifically developed for outdoor use. When the system starts up, the temperature control system integrated in the weatherproof, climate-controlled housing makes sure the operating temperature has been reached before components such as the receiver, direction finder and control PC are turned on. If necessary, the internal heater is switched on. If the internal temperature rises above the maximum operating temperature, due to continuous exposure to strong sunlight for example, the temperature control system automatically turns off components to prevent damage from overheating. They are only put back in operation when the temperature has returned to an uncritical level.
Internal fans provide constant air flow which distributes waste heat over a heat exchanger to the external walls where it is dissipated via cooling fins.
A weather protection cover (R&S®UMS20-B4) can be used to increase the operating temperature range. The cover protects the R&S®UMS200 from direct sunlight and is available as an accessory. The cover comes with integrated fans that improve the dissipation of waste heat via the cooling fins.
