Frequently Asked Questions

What is an S parameter test?

An S-parameter test measures how RF energy is transmitted and reflected between the ports of a network, such as an antenna or RF component. Using a vector network analyzer, engineers capture data on reflection (return loss) and transmission (insertion loss) across a defined frequency range, providing a complete picture of a device's electrical performance.
