Method and apparatus for nondestructive testing of a gas discharge tube

摘要

A method and apparatus for nondestructive testing of a gas discharge tube (GDT) comprising: electrically connecting a first terminal of the GDT to a first port of a vector network analyzer (VNA); electrically connecting a second terminal of the GDT to a second port of the VNA; measuring S parameters with the VNA; determining GDT capacitance and insertion loss based on the measured S parameters; comparing the determined capacitance and insertion loss of the GDT with a threshold value to determine if the GDT is functional.
