Portable Decimator D3
SED’s Portable Decimator D3 is a third generation spectrum measurement and analysis
product providing high-end performance at a
low price. It is conveniently packaged for use
by field technologists or it can be installed
anywhere in a satellite, cable or terrestrial
wireless network. It is a small enclosure easily
transported in a typical laptop case. It can be
connected to any AC power source worldwide. The powerful GUI is available using any
standard web browser.
The Portable 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. Portable Decimator D3 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 1.5 MHz. The
Portable Decimator D3 can be connected to an external 10 MHz reference for improved frequency accuracy and
stability. All data communications with the Portable Decimator D3 occurs via its built-in Ethernet port.
It can be easily transported anywhere, providing an instant 5 MHz to 3 GHz spectrum analyzer, in conjunction with a laptop and any web browser.
The 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. It 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.
When installed in a facility, the Portable Decimator D3 provides network access to all 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.
