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 

  • Hardware-in-the-Loop (HiTL) interfaces provide analog RF connections for  physical devices

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.

DYSE emulates operationally realistic operating environments so users can validate concepts, refine capabilities, and assess performance through Modeling & Simulation before proceeding to  physical device Test & Evaluation and/or field testing.
