The 22 Series Open/Shorts are used on the test port of an SWR Autotester or SWR bridge to establish a full reflection reference for accurate SWR measurements. When used with scalar network analysers, the open and short reflections over a swept frequency range can be automatically averaged to enhance measurement accuracy. All models consist of an open on one end and a short on the other. Features: Single gold-plated component providing full open and short reflections for accurate SWR measurements; DC to 50 GHz frequency coverage;GPC-7, Type N, WSMA, K Connectors and V Connectors; 50 Ohms or 75 Ohms impedance.
