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.

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 RF Channel Emulator](https://static.wixstatic.com/media/801d82_1c4a31572ea04bdc9c915f4c4547c6fe~mv2.png/v1/fill/w_171,h_171,al_c,usm_0.66_1.00_0.01,enc_auto/Wisp%20no%20green.png)
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.

Users can create test scenarios consisting of physical and virtual nodes. Any and all nodes can be “placed” on terrestrial, airborne, or space platforms with associated antenna patterns and 6 DOF motion. The DYSE® channel emulator models the RF propagation paths between nodes, introducing a wide range of operationally correct propagation effects.
