R&S®ESMD Wideband Monitoring Receiver

Premium-class signal reception

Nationwide networked system for ITU-compliant radiomonitoring
  • Networking of civil regulatory authorities' radiomonitoring nodes, e.g. with R&S®ARGUS 6.1 and suitable options
  • Automatic identification of deviations between actual and predefined spectral values
  • Guided measurements with R&S®ARGUS 6.1 – even for inexperienced users
  • Audio demodulation and processing
Searching for interference sources in the air traffic control (ATC) band
  • Finding and eliminating of interfering signals to maintain security-critical aeronautical radiocommunications
  • Monitoring of entire aeronautical radio band (approx. 20 MHz) within realtime spectrum
    • Easy detection of pulsed, frequency agile and sporadic interferers
  • Audio monitoring of occupied channels to test audio transmission quality using the frequency scan
Radiomonitoring for security authorities and organizations
  • Networking of several receiving stations to create a temporary networked system, e.g. with R&S®RAMON and suitable options
  • Multiple receiver concept: parallel search, detection and generation of content
  • Central control station to oversee the success of public safety and security operations
Multichannel recording of security-critical voice communications
  • Continuous recording of voice communications
    • Parallel transmission of up to 128 channels
    • 25 kHz/8.333 kHz bandwidth per channel (ATC band)
    • All parallel channels within receiver's realtime bandwidth
    • Data transmission using I/Q baseband data output on 1 Gbit LAN interface
    • AM demodulation and recording using a PC and software application, e.g. R&S®CA120 with suitable options
    • Recording of voice content as a digital audio file (*.wav)
Signal analysis of a communications channel with unknown content
  • Online signal analysis with live streaming over LAN interface, e.g. with R&S®CA100 and suitable options
    • Signal analysis and classification
    • Detection of modulation mode and transmission quality (eye diagram)
    • Extraction of signal content using bitstream analysis
  • Offline signal analysis of recordings
Interception of frequency hopping radios in tactical communications
  • Neutralization (dehopping) of frequency hopping to protect against unwanted monitoring
  • 80 MHz realtime bandwidth to cover the entire tactical communications band
  • Data transmission to recording medium via 10 Gbit LAN interface, e.g. with R&S®GX465
  • Offline analysis of data stream, e.g. with R&S®GX410 and suitable options
    • Separation of different radios transmitting at the same time
    • Combination of individual frequency packets of the same radio (dehopping)
Analysis of radar signals
  • Determination of simple radar parameters using spectrum, waterfall and marker
    • Determination of center frequency, rotation time and pulse parameters
    • Measurement of signal level using wideband demodulation path
  • Detailed analysis of radar parameters using the R&S®TPA technical pulse analysis software
