R&S®ESMD Wideband Monitoring Receiver - 7

Nationwide networked system for ITU-compliant radiomonitoring Networking of radiomonitoring nodes of civil regulatory authorities To perform civil regulatory authorities' radiomonitoring tasks in line with ITU recommendations, all available receiving nodes must be networked. This includes both stationary and vehicular radiomonitoring stations. The R&S®ARGUS monitoring software is ideal for networking and remotely controlling nationwide radiomonitoring systems as well as small regional networks. Interference can be quickly and effectively located and eliminated, even in a frequency spectrum...

R&S®ESMD Wideband Monitoring Receiver - 8

Searching for interference sources in the air traffic control (ATC) band Fast detection and elimination of interfering signals to maintain security-critical aeronautical radiocommunications The ATC radio band contains all security-critical radiocommunications necessary to control national and international aircraft movements. Interference in this approx. 20 MHz wide frequency spectrum can quickly lead to critical situations. It is necessary to constantly monitor this frequency range in order to quickly detect and eliminate unauthorized emissions and wideband interference. Monitoring of...

R&S®ESMD Wideband Monitoring Receiver - 9

Radiomonitoring for security authorities and organizations Networking of several receiving stations to create a temporary networked system Monitoring station setups must be flexible in order to support local radiomonitoring tasks in both stationary and mobile applications. The R&S®RAMON radiomonitoring software was specially developed for networking receiving stations to create a temporary networked system. The software optimizes radiomonitoring of security-critical zones, for example by collecting spectra or demodulated audio content. Multiple receiver concept: parallel search, detection...

R&S®ESMD Wideband Monitoring Receiver - 10

Multichannel recording of securitycritical voice communications Continuous recording of voice communications In many cases, it is useful to continuously record voice communications (e.g. aeronautical radiocommunications) for later use (e.g. for investigations after a plane crash). Spoken information is therefore constantly recorded. Since multiple channels are simultaneously occupied in the ATC band, all active channels must be demodulated and recorded in parallel. Parallel transmission of up to 128 channels The R&S®ESMD provides up to 128 parallel channels for the continuous recording of...

R&S®ESMD Wideband Monitoring Receiver - 11

Signal analysis of a communications channel with unknown content Online signal analysis with live streaming over LAN interface The R&S®ESMD provides a continuous I/Q baseband data stream for online analysis of a max. 1 MHz signal channel over the 1 Gbit LAN interface. The R&S®CA100 software uses this data stream to analyze and classify the signal on an external PC. It recognizes modulation modes and displays transmission quality in an eye diagram, for example. Bitstream analysis allows users to extract the message content from the received signal. If the wideband monitoring receiver is...
