SED Systems is an established full-service communications technology development company, and we’ve been providing the Telecommunications industry with innovative satellite, cable and terrestrial wireless communication solutions for over 45 years.
SED provides engineering design services, in-house manufacturing, contract build-to-print services and test solutions. Our FPGA-based designs are engineered to help customers differentiate themselves, expedite time to market and deliver “future proof” solutions. SED offers innovative and practical solutions for our customers’ demanding and complex requirements, delivered on-time and within budget.
SED provides full turnkey services to meet all your RF System needs. Our systems engineering approach meets the most demanding requirements in harsh environments for frequency ranges up to and including Ka band and Q&V bands.
We support you through the full system life cycle from requirements analysis, site preparation, and equipment specification, through system design and integration, test and on-site commissioning, training and long-term support.
Extensive use of COTS equipment minimizes cost, technical risks and development time. Custom hardware and software designed by SED ensures unique requirements are satisfied effectively and efficiently.
Decimator D3 Spectrum Analyzer
SED’s Decimator D3 Spectrum Analyzer remotely monitors communication signals anywhere RF signal monitoring is required. With a frequency range of 5 MHz to 3 GHz, the Decimator D3 provides accurate and fast measurements at a compelling cost.
• Available in 3 form factors – PCIe card, portable and multi-port
• Powerful & easy to use with a standard internet connection, no training required
• Built-in Cross-pol and Carrier Monitoring applications
• CarrierWatch add-on provides the ability to view multiple carriers in a single window & more
• Programmable email and SNMP alarms
• Built-In multi-user support with up to 10 concurrent users
• Powerful API specifications for integration with third-party NMS’s
When used standalone or integrated into your solution, Decimator D3 is ideally suited for measurement of communications and broadcast carriers. Our Remote Management Protocol can be integrated into your network, RF system/unit, or RF monitoring/measurement system.
Gateways & Planning Systems
Our range of world-class Satellite Capacity Planning and Resource Management solutions ensure your valuable spectrum resources are allocated effectively to meet the demands of your customers. We specialize in providing solutions to the satellite communications industry, including the design and delivery of software solutions used for the planning, management, and operations of satellite communications networks.
We offer both off-line planning tools and real-time on-demand allocation systems, thereby ensuring that your resources are efficiently utilized both globally at the constellation level down through individual satellites, beams and carriers.
Our line of satellite modulators and related products include the Gemini modulator, Defender and Hercules multi-channel modulators, the narrow-band SDTS modulator, the Itus L-band redundancy switch, and beacon generators.
The Gemini modulator provides DVB-S/S2/S2X, DSNG and Turbo functionality and includes ASI and IP inputs and both IF and L-band outputs.
Our Itus modulator redundancy switch provides 1:1 modulator L-band redundancy switching for our modulator products. Itus includes our patented Intelligent Switching mode functionality.
The narrow-band SDTS modulator supports the Inmarsat SES28B standard, while our Beacon Generator provides an L-band output that can be frequency converted to the band you need.
Our Hercules & Defender multi-channel modulators are designed to generate multiple channels out of a single one rack-mount unit (1RU) chassis. Did you know that 1 of SED’s multi-channel satellite modulators can replace as many as 16 traditional modulators? The small form factor provides significant savings in capital costs, reduced operating expenses & other benefits.
Our modulators have a flexible FPGA-based design that can be leveraged to deliver custom modulators for non-standard encoding and modulation types. SED also offers private labelling for OEM products.
Distributed Access Architectures (DAA)
SED has solutions for all Distributed Access Architectures (DAA). With a mature IP portfolio of Remote PHY DOCSIS technologies and advanced signal processing algorithms, SED offers powerful and dynamic solutions for our customers.
