Sliding Terminations
Modular Connectors Description The 2507 and 2517A are high precision, movable, low-reflection, broadband terminations for making precision measurements in frequencies ranging from 0.9 to 18 GHz. They are true modular instruments since they are provided with interchangeable LPC7 and type N (female and male) connectors. Optional precision adapters for other connectors are also available. Both terminations are provided with beadless (air dielectric) connectors and feature movable center conductors which can, with the aid of an appropriate connector gage, be set for a flush interface condition. Both models and accessories are provided in foam-lined wooden instrument cases.
