With an increase in customer database all broadcast companies are adding more channels and using multiple satellites. Nowadays, a typical earth station will consist of many satellite dishes, all of which need to be monitored in real time.

In order to provide good customer experience, it is necessary to monitor signal quality continuously. Use of multi satellites and their monitoring is possible with right tools only.

Nowadays, multiport input remote spectrum monitors are available which make broadcast companies'/satellite operators' job easy. The multiport remote spectrum monitor enables the spectrum of each satellite uplink or downlink to be monitored for spectral purity and the presence of interferers. Alarms can be automatically triggered on detection of unwanted interference that would degrade the signal integrity.

Remote spectrum analyzers are designed to identify and locate interfering signals. This serves to keep satellite communication channels clear - a key goal for satellite operators. This translates into customer loyalty, reduced customer churn, and a superior brand. Remote monitor must be able to capture many types of signals including periodic or transient transmissions as well as short bursty signals. Higher FFT bandwidths available on these remote spectrum monitors provide the ability for wideband real-time captures of signal activity for subsequent post-processing. IQ captures can be recorded both in block mode or streamed.

Remote spectrum monitors must have certain key features:{mosimage}

  • Multiple input to monitor uplink and downlink separately
  • Integrated GPS receiver for monitoring location and time synchronization applications
  • Gigabit Ethernet available for high-speed communications
  • Measurements: Occupied bandwidth and channel power
  • Interference analysis: Spectrogram and signal strength
  • Fast sweep speed
  • Should be able to capture low-intensity signals as well
  • Software for data processing and analysis

Key Benefits of Remote Spectrum Monitoring

  • Automation and scalability
  • Highly automated process to help minimize expenses while preserving network integrity
  • Monitoring software or your own applications; users can identify patterns of interference, record a spectrum history and geo-locate the sources of problem signals
  • Easily add additional monitors as the need for interference mitigation grows
  • New features and options can be added remotely
  • No site visits required

Key Applications

  • Network interference monitoring
  • Geo-location of interference signals
  • Maintaining history of spectrum activity
  • Setting power threshold levels to automatically generate alarms
  • Generating records of interference events for potential legal action
  • Spectrum occupancy measurements

Signals of Interest

The wide variety of signals to be monitored falls into several categories. Each of these types of signals is examined in some detail. These include:

  • Intentional interference (including illegal or unlicensed broadcasts)
  • Accidental interference
  • Occupancy

Integrated Web Server

Using an Internet browser (Chrome and FireFox are supported), a user from anywhere in the world can login to the spectrum monitor and control any of its features. This includes such parameters as frequency settings, RBW/VBW control, reference-level configuration, and many other settings relevant to the user's spectrum-monitoring application. Trace data, spectrograms, and other measurements can be viewed inside the browser window. A key advantage in using the web server is that it is platform-agnostic. Any electronic device capable of rendering a browser must work with the web server.
