VNA Everywhere, VNA Everything: The History and Evolution of the Modern Network Analyzer, and Why SATCOM and 6G Need It

Speaker: Joel Dunsmore, R&D Fellow, Keysight Technologies

The network analyzer is one of the most iconic and indispensable tools in microwave engineering — yet few instruments have evolved as dramatically over time. In this plenary presentation, Joel Dunsmore, R&D Fellow at Keysight Technologies, will take us on a fascinating journey through the history and evolution of the modern Vector Network Analyzer (VNA).

From its beginnings as a fast, sweeping power meter to today’s precision workhorse of advanced measurement systems, the VNA has continuously transformed alongside the technologies it supports. Joel will highlight the key innovations and breakthroughs that shaped its development — innovations that now make the VNA indispensable for next-generation applications, including SATCOM and 6G sub-THz systems.

The talk will also look ahead, exploring emerging trends and future needs in test instrumentation as we push further into the era of ultra-high-frequency communications.

Join us for this insightful session that connects the legacy, present, and future of one of our field’s defining instruments!
