Paradise Datacom LinkGuard allows automated 24/7 modem interference detection

Teledyne Paradise Datacom is proud to announce LinkGuard™, its patent-pending technology for detecting in-band interference underneath satellite carriers.

LinkGuardTM, which is now available on all Paradise satellite modems, allows the rapid diagnosis of ‘signal under carrier’ type of interference while remaining on traffic. A visual indication of any unwanted interference is provided through a signal-under-carrier spectrum web graph (showing the wanted carrier along with any unwanted interference). The graph includes a ‘persistence’ mode to show even intermittent interference.

However, LinkGuard™ takes detection one stage further by providing a user-set power spectral density threshold, above which the modem will automatically alarm to indicate that a significant source of interference has been detected. Interference status information is therefore provided via this alarm, which is available locally on the modem as well as remotely via a web server, SNMP traps and physical contact relays. This feature therefore provides automated 24×7 interference detection without the need for an operator to be present.

Ericsson Voyager II Multiformat HD MPEG-4 DSNG Encoder

 

Ericsson Televisions Fifth Generation DSNG Encoder

Voyager II is Ericsson’s fifth generation DSNG Encoder. It is the most flexible and scalable news gathering product on the market, reflecting Ericsson’s technology leadership and unique heritage in a market segment we created 15 years ago with the launch of the world’s first DSNG encoder.

DSNG is one of the most demanding segments in the broadcast world, with requirements for solutions to be fully integrated, deliver maximum performance and be fully adaptable while giving the highest levels of equipment interoperability. Voyager II excels in all these areas, delivering the best return on investment to operators and service providers through the widest range of software upgrade paths and expansion options.

Based on our in-house technology, Voyager II is built upon a new and revolutionary modular chassis design in a spacesaving 1RU form factor with up to six hot swappable option slots. It supports a comprehensive range of processing options, including the highly flexible, multi-standard, multi-format “x-series” range of encoders, making it the first DSNG to unleash the power of MPEG-4 AVC 4:2:2 encoding with 10-bit precision at up to 1080p50/60 resolutions. An integrated satellite modulator offers high order DVB-S and DVB-S2 modulation on both IF and L-Band outputs.

Voyager II features a fully functional front panel that provides users maximum control of this incredibly flexible unit. Based on industry feedback it introduces a bottom-up re-engineered hardware and menu structure, allowing fast access to the most common SNG operations, easy monitoring of incoming audio and video signals and a level of operator’s customization, while maintaining the all-important familiarity with today’s most popular SNG units.

Voyager II represents the most advanced DSNG unit on the market, offering broadcasters, operators and service providers the level of integration, flexibility and scalability necessary to future-proof any operational investment during today’s technology migration.

Xicom XTD-750K 750W Antenna Mount Ku-Band TWTA

The Xicom XTD-750K is a compact, self-contained, antenna mountable power amplifier designed for low cost installation and long life.

The XTD-750 design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self-contained within the High Power Amplifier (HPA). These features provide high reliability, low maintenance costs, and low replacement costs.

The XTD-750 uses high efficiency, dualstage collector Traveling Wave Tubes (TWT). Some benefits of this type of tube are:

  • Reduced prime power consumption
  • Lower internal operating temperatures
  • Reliability enhancement

These benefits are obtained for both the linear and saturated modes of operation.

The XTD-750 incorporates power factor correction circuitry, which minimizes line current distortion and reduces the required Volt-Amps. The combination of power factor correction and high efficiency TWTs reduces input Volt-Amps by 45% when compared to equivalent amplifiers. A high frequency resonant conversion power supply is used that accepts a wide range of prime power (180 to 260 VAC). the automatic features of the power supply include quick recovery from prime power outages and multiple helix arc fault resets (three fault cycles).
