Sliding Terminations
Metrology Grade Description These metrology grade sliding terminations achieve a high level of accuracy, stability and repeatability as impedance standards for calibrating vector network analyzers (VNAs) and in other critical, precision measurement applications. These instruments feature a one-piece inner and outer conductor with a seamless, integral, beadless (air dielectric) connector that provides an extremely accurate impedance reference. An external jacket enhances thermal stability by insulating the transmission line. When used with "thread-on" connector gages, a "flush set" mechanism allows center conductor adjustment for a coplanar inner and outer conductor interface at the connector mating plane. The 8034( ), 8777( ), and 8834( ) terminations (3.5mm, 2.92mm and type N, respectively) feature a "pull back" mechanism which automatically locks the center conductor to a previously set flush condition, and thereby aids in achieving a flush connection. Terminations with sexed connectors are available in female and male versions, or as a set. The 8034A 3.5mm and the 8834A type N female termination also features a precision slotless center conductor contact for optimum accuracy.
