Description

These metrology grade sliding terminations achieve a high level of accuracy, stability and repeatability when used as impedance standards for calibrating vector network analyzers (VNAs) and in other critical, precision measurement applications.

They feature seamless, integral, beadless (air dielectric) connectors that provide an extremely accurate impedance reference, and an external jacket that enhances thermal stability by insulating the transmission line.

When used with “thread-on” connector gages, a "flush set"4 mechanism allows users to adjust the center conductor to achieve a coplanar inner and outer conductor interface at the connector mating plane.

A "pull back"5 mechanism automatically locks the center conductor to a previously set flush condition, making it easy to return to flush condition from any other position. These terminations are available individually, with female or male connectors, or in boxed sets with one each of both sexes, per the Specifications chart (below).

TNC terminations are precision air lines with low-reflection transformers to the dielectrically loaded connectors. Their air dielectric connectors and movable center conductors permit precision setting of the connector interface condition, using an appropriate connector gage.
