SED Systems Decimator D3 Digital Spectrum Analyzer Card

Summary

SED’s Decimator D3 is a third generation spectrum measurement and analysis card providing high-end performance at a low price. It can function as either an independent spectrum analyzer in a satellite, cable or terrestrial network or can easily be integrated into a satellite terminal, equipment enclosure or as part of a larger measurement network.

Decimator D3 uses state of the art digital technology and Fast Fourier Transformations to make lightning fast and accurate measurements. With a very low noise floor and large dynamic range, it is well-suited to measure any type of satellite, cable or terrestrial wireless carrier, including very small carriers, beacon signals and for carrier monitoring applications. Decimator accepts all signals from 5 MHz to 3 GHz and input power levels ranging from –110 to +5 dBm. RBW varies from 1 Hz to 15 MHz. 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.

It is only 4” x 7” x 0.8” and is therefore ideal for integration into small spaces. It can be installed in any
enclosure or computer chassis. It is a half size PCI express (PCIe) card and can be installed in an available
computer PCIe slot, providing power to the card. Alternately, it can be mounted on standoffs and powered
through a 3-pin connector (12 and 3.3 to 5 Vdc) for integration into any enclosure.

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 GUI also includes a powerful built-in Carrier Monitoring
function, which provides notification via email or SNMP of carrier measurements that exceed user-defined limits, offering you peace of mind that up to 100 of your carriers are operating as expected.

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.
