REGISTER NOW: Mastering EVM: Fundamentals Webinar

Error vector magnitude (EVM) is one of the most critical performance measurements in today’s wireless digital communication systems. As modulation schemes grow more complex and bandwidth demands continue to expand, achieving and verifying accurate signal transmission becomes essential. This webinar provides a clear, practical introduction to EVM and its role in evaluating modern digital modulation quality.

Attendees will begin with a foundation in digital modulation theory, including how data symbols are mapped to constellation points and transmitted over a channel. From there, the session breaks down the concept of EVM—showing how deviations between ideal and actual symbol locations directly quantify signal integrity and system performance. Real-world factors such as noise, phase noise, IQ imbalance, nonlinearities, and timing errors will be examined to illustrate how they contribute to increased EVM.

A key focus will be interpreting constellation diagrams, one of the most powerful tools for visualizing modulation accuracy. Participants will learn how to recognize error patterns, isolate probable sources, and use these insights to improve system design, calibration, and troubleshooting workflows. Examples will highlight applications in 5G, Wi-Fi, satellite links, IoT devices, and advanced RF test environments.

Whether you are new to advanced wireless test concepts or looking to sharpen your analysis skills, this session delivers foundational knowledge and diagnostic techniques to help engineers validate and optimize digital communication systems. Leave with the confidence to interpret EVM results, identify performance issues, and apply constellation-based insights to ensure robust, high-quality signal performance.
