IEEE Portugal Joint Chapter AP/MTT/EDS and the Instituto de Telecomunicações are pleased to invite the community to a Distinguished Microwave Lecture by Dr. Joel Dunsmore, a leading expert in advanced measurement systems and Keysight R&D Fellow.
Modern Vector Network Analyzers (VNAs) have evolved far beyond traditional S-parameter measurements. Equipped with flexible hardware and powerful software, today’s VNAs offer unmatched precision across a broad spectrum of applications. They function as multi-functional test systems, enabling in-depth characterization of devices and signals, from noise figure and gain compression to phase noise, mixer performance, and frequency converter analysis.
Recently, Vector Spectrum Analysis (VSA) capabilities have been integrated into VNAs, allowing precise measurements of complex modulated signals, such as Error Vector Magnitude (EVM), Adjacent Channel Power Ratio (ACPR), and Digital Pre-Distortion (DPD) characteristics. These advancements enable high-frequency mm-wave and sub-THz measurements with unprecedented accuracy, including demonstrations at 250 GHz using 20 GHz bandwidth modulated signals.
This lecture will explore these advanced methodologies and configurations that push the limits of microwave component characterization, showcasing how next-generation VNAs deliver insights beyond the reach of conventional instruments.

Have you ever wondered how open source really works? Are you intrigued by licenses and governance models? Or how you can get involved in the open source community? How does it really drive innovation in practice?
In this session, you will get an overview of open source, open source licenses, and how EU projects leverage Open Source in various ways, guided by the expertise of the Eclipse Foundation. You will also see how the Eclipse Foundation facilitates standardization efforts by looking at how the Jakarta EE specifications are developed under the Jakarta EE Working Group hosted at the Eclipse Foundation.
At the end of the session, there will be a direct opportunity to engage with a panel of open source experts and ask any questions you might have.
The event will take place on November 12th, 2025, from 14:00 to 17:00, at Instituto de Telecomunicações (Auditorium), Aveiro, Portugal, with the invited speakers:
