Test Port Cables & Adaptors


Rosenberger offers a wide test port portfolio of cable assemblies, ruggedized adaptors and an interchangeable port system for vector network analyzers (VNA) up to 90 GHz:

Test port cables providing outstanding phase and amplitude stability are also available as sets containing two cables with a standard length of 60 cm each. The range is optimized for frequencies up to 12 GHz, 18 GHz, 26.5 GHz, 40 GHz, 50 GHz, 70 GHz and 90 GHz. VNA test port cables are also available as cable sets, containing two cables of 600 mm standard length, and are supplied in high-quality wooden boxes.

Test port adaptors are designed to connect directly to the VNA test port via a ruggedized coupling nut. They are available in the RPC-3.50, RPC-2.92, RPC-2.40, RPC-1.85 and RPC-1.35 connector series. Available as "in series" and "inter series" versions, their ruggedized construction ensures reliable protection of VNA test ports and reduces mechanical abrasion to a minimum.

Interchangeable port connectors are designed for test equipment applications using test ports that will be continually mated and re-mated. This has been achieved by the development of an interchangeable port connector system featuring a panel mounting half and an innovative neutral interface, allowing a high number of mating cycles without causing possible damage to the equipment device interface.
