Equipment info

The 83059K is a precision 3.5 mm coaxial adapter kit designed for RF and microwave test and measurement applications. This three-piece kit includes male-to-male (83059A), female-to-female (83059B), and male-to-female (83059C) adapters engineered to deliver superior RF performance across demanding test environments. The adapters function as connector savers, protecting expensive test port connectors from damage while enabling seamless interconnection in complex setups. Ideal for adapter swap calibrations on network analyzers, particularly when characterizing non-insertable devices, the 83059K maintains measurement integrity through its instrument-grade construction and exceptional electrical performance.
