IoT, 5G, connected cars drive VNA applications

摘要

Once considered arcane laboratory instruments operated by experts, vector network analyzers are going mainstream. While expensive, high-performance instruments with frequency ranges beyond 1 THz have a key role to play, lower cost, easier-to-use alternatives are placing VNA technology in the hands-literally in the case of the more portable versions-of a variety of engineers who may use the instruments only sporadically. Today's VNAs are available in a variety of form factors and architectures-including handheld USB versions, PXI modules, and benchtop configurations.
