Microwave measurement with Joel Dunsmore

What this episode covers

Joel Dunsmore, a Keysight Fellow and original designer of the HP 8753 VNA, explains the evolution of vector network analyzers from single-box instruments to high-port-count modular systems. He details the critical role of calibration, error correction, and the physical realities of RF components like APC7 connectors and coaxial cables in achieving accurate measurements. The discussion covers modern challenges in 5G and SATCOM testing, including the use of multi-port analyzers for phased arrays and the integration of spectrum analysis capabilities within VNAs to improve manufacturing throughput.
