Comtech EF Data MBT-5000 L-Band Up/Down Converter System

Posted on by
The Comtech MBT-5000 Up/Down Converter System provides frequency conversion between L-Band IF and C-/X-/Ku-Band RF frequencies.

The RF marketplace has been transitioning from traditional 70/140 MHz IF-based networks to systems using L-Band (950 to 2000 MHz) for the modem/RF equipment link. The MBT-5000 Up/Down Converter System provides this frequency conversion between L-Band IF and C-/X-/Ku-Band RF frequencies. Featuring a drop down front panel providing access to two “hot swappable” frequency conversion modules, this unit offers either a mix of conversion functionality or 1:1 redundant system operation.

Designed for rack mounting , the MBT-5000’s 1RU 19-inch chassis front panel contains all operator controls, indicators and displays for local and remote with RF, IF, power, and communications interfaces on the rear. When configured with the redundancy option, the main chassis contains two diode “OR-ed” internal power supplies for increased reliability along with the necessary IF/RF switches. Providing the level of RF frequency conversion performance that has historically been associated with 70/140 MHz rack mount converter systems, the MBT-5000 provides a smooth IF infrastructure upgrade path.

MBT-5000 Features
Meets or exceeds IESS-308/309
Facilitates 188-164A system compliance
Low phase noise
Powerful M&C support
Ethernet/Telnet/SNMP
EIA-232/485
Flexible configuration
RF Band switching in minimal time without requiring tools
Available 1:1 redundancy in a 1RU chassis (MBT-5000) or a 3RU chassis (MBT-5003)

Paradise PD155i Satellite Modem/IP Router

Posted on by
The Paradise PD155i 155Mbps IP Satellite Modem/ Router offers an extensive range of network management and bandwidth optimization features.

A 4-port Gigabit Ethernet switch, advanced routing and Quality of Service protocols are supported as part of the feature-rich IP functionality.

Traffic shaping allocates bandwidth in a controlled manner between competing data streams. This allows data services — including the satellite portion of the link — to be fully provisioned end-to-end rather than being simply ‘best effort’.

Large bandwidth reductions are achieved using a range of data compression and acceleration techniques. Paired Carrier (incorporating ViaSat’s patented PCMA technology) can further halve satellite bandwidth requirements.

State-of-the-art forward-error-correction (FEC) technology includes Turbo and LDPC. Lowlatency FastLink LDPC is attractive for lowdata- rate links. Single/multistream DVB-S2 is also supported.

Embedded satellite and IP diagnostic tools are included and are the most sophisticated available on the market.

The PD155i is fully compatible with all other Quantum-series modems in IP closed modes.

SED’s Decimator D2 Second Generation L-Band Spectrum Analyzer

Posted on by
SED Decimator D2’s improved low noise floor and dynamic range, combined with a powerful new
Graphical User Interface, make it the ideal low-cost solution for local or remote spectrum analysis
within a satellite terminal, enclosure or earth station.

Decimator is the smallest card on the market and is ideal for integration into small spaces. It can be installed in any enclosure or computer chassis. It is a half size PCI card and can be installed in an available computer PCI slot, providing power to the card. Alternately, it can be mounted on standoffs and powered through a +12/+5 Vdc 3-pin connector for integration into any enclosure.

It uses state of the art digital technology and Fast Fourier Transformations to make quick and accurate measurements. With a very low noise floor and large dynamic range, it is well-suited to measurement of any type of satellite carrier, including very small carriers, beacon signals and for carrier monitoring applications. Decimator accepts all L-band signals from 950 to 2,150 MHz and input power levels ranging from -110 to +5 dBm. RBW varies from 4 Hz to 500 kHz. The Decimator can be connected to an external 10 MHz reference for improved frequency accuracy and stability. All data communications with the Decimator occurs via its built-in Ethernet port.

The Decimator’s powerful Graphical User Interface (GUI) is available using any standard web browser. No additional software is required. The GUI is very easy to use and operates like most traditional spectrum analyzers. It provides user-selectable colors for markers and traces, allows storage of multiple traces and provides measurement reporting.

The Decimator provides network access to all technical staff connected to the facility network or a corporate wide area network. This allows all technical staff the ability to monitor feeds and carriers at any time and from any location in the world using only a web browser.

For integration into a satellite terminal or measurement system, the Decimator can be operated via its built-in GUI or the user can create a separate user interface using the publicly available API. An SNMP status interface is also provided.
