Dynamic Spectrum Environment Emulator (DYSE)
The Dynamic Spectrum Environment Emulator (DYSE) is a RF channel emulator that seeks to imitate realistic RF environments, including congested and contested conditions. RF paths can be individually programmable, and emulate the impact of real-world operational conditions, in the safety and convenience of a lab environment. DYSE supports the full RF Systems Development Life Cycle from RF Modeling and Simulation to Testing and Evaluation.
RF Channel Emulator Test And Simulation Systems
- Emulate Realistic RF Environments
- RF Modeling & Simulation (M&S) and RF Hardware-in-the-loop (HiTL) Testing & Evaluation (T&E)
- RF Digital Twin performance testing
- RF Virtual Reality creation. Dynamically emulates realistic RF environments, including congested and contested conditions
- High-Fidelity, repeatable RF systems testing in the lab with real-world field quality characteristics
- Development and testing asset optimized for modern RF technology like SDRs
- Scalable to support user capacity needs, small to massive RF scenarios
- Supports accelerated RF development and time-to-field
- Supports Virtual Nodes (VSUs: virtual models of systems) and/or Physical Nodes (PSUs: Real systems that can be connected to DYSE for test and simulation purposes)
- Tested for 5G, Spectrum sharing, Resilient PNT, Cognitive Radio, Tactical and LPI/LPD communications systems, EW systems, and more
How It Works
- RF devices under test interconnect through synthetically generated RF environments
- RF paths between devices emulate the impact of real-world RF operational conditions – paths are individually programmable
- Physical devices can interact with virtual devices – full-mesh interconnection
- Device interactions take place through the DYSE Virtual RF Environment (VRE) at digital baseband
- RF Hardware-in-the-Loop (HiTL) interfaces provide analog RF connections for physical devices
RF Modeling And Simulation With DYSE
DYSE can be used to develop and refine RF designs, concepts, applications, and algorithms. When performing Modeling and Simulation, DYSE passes data produced by RF device models through mathematical and statistical channel models to predict performance under user-selected RF operating environments.
The DYSE RF channel emulator emulates operationally realistic operating environments so users can validate concepts, refine capabilities, and assess performance through RF Modeling & Simulation before proceeding to physical device Test & Evaluation and/or field testing.
Following M&S Assessment, developers can instantiate pre-prototype physical systems on the Parsons WISP Systems.
Testing And Evaluation With DYSE
DYSE is available in configurations to test and assess physical RF devices and systems in user-controlled emulated RF environments. With both M&S and T&E testing capability, DYSE provides a versatile platform for accelerating RF systems development and time-to-field while decreasing risk.
