The R&S® UMS400 universal monitoring system can be used for spectrum monitoring and radiolocation from 8 kHz to 8 GHz and can be extended to 20 GHz with the R&S CS-MC20 converter. The compact outdoor housing allows a wide range of use cases including event monitoring and temporary missions in remote areas. The increasing frequency range of wireless communications services requires monitoring up to 8 GHz and in some cases even up to 20 GHz. This typically requires installing the monitoring sensor close to the antennas to keep cable losses low, and the R&S UMS400 and R&SCS-MC20 can achieve this as they have outdoor-compatible housings. Monitoring and single-channel DF antennas and time difference of arrival (TDOA) and angle of arrival (AoA) radiolocation are available.
