The 34946A module is a microwave switch for the Keysight 34980A basic device. It enables bidirectional switching of a signal with a bandwidth from DC to 26.5 GHz. These switches are characterized by excellent specifications for insertion loss and for the voltage-standing wave ratio. The microwave switch is designed as a 1x2 changeover switch. For general applications, this microwave switch is e.g. B. suitable to switch different signal sources to an input of a module to be tested (DUT / Device Under Test) such as receivers, transmitters or converters.
