White Paper Overview

Part 2: Electromagnetic Environmental Simulation Architectural Overview

This white paper dives into the system architecture required to generate complex electromagnetic environments for EW receiver evaluation. It examines how PDWs define pulse-modulated signals, the synchronization challenges of overlapping multi-emitter scenarios, and the importance of aligning time, amplitude, and phase across all channels. The paper also contrasts analog versus digital signal combination and discusses best practices for LO and clock distribution to ensure realistic and repeatable testing conditions.
