With the increase of wireless and connected devices there is a rapidly expanding need for component testing to ensure the optimal performance of these devices. The resources below are designed for people without a background in VNAs. This content will provide an introductory understanding of testing wireless or IoT devices for R&D, development, and production.
When working with a multiport or differential circuitry application, a 2-port VNA might not be suitable for your measurements. In this scenario, using a 4-port VNA is more effective for making accurate measurements. Many applications of a VNA require multiport or differential circuitry. This video explains how to use a 4-port VNA to make such measurements, while explaining the benefits of performing balanced measurements with a 4-port VNA.
