Measuring Insertion Loss, Return Loss, and Gain with a VNA

Visão geral

The measurements of insertion loss and return loss help characterize an RF component.The unique architecture of the vector network analyzer, or VNA makes it easy to take these measurements, with a high degree of accuracy. Covered in the presentation are: definitions for insertion loss / return loss, a high level overview of the architecture of a VNA, and how the VNA's setup makes it nicely suited for measuring insertion loss / return loss.
