Stepping up to a vector network analyzer for loT design optimization

摘要

With the acceleration of Internet of Things (IoT) devices and the proliferation of RF and wireless products, there is a growing need for RF measurement expertise and affordable RF test instrumentation. Until recently, vector network analyzers (VNAs) have been too expensive and hard to use for IoT and other embedded applications where they can be quite useful for design verification and optimization. That is now changing with the introduction of affordable, compact USB-based VNAs. Here, we'll walk through VNA operation, discuss how they compare to spectrum analyzers, outline several key application areas, and look at how the emergence of IoT applications is changing RF instrumentation.
