摘要： A system for injecting noise signals onto power generated by a power source comprising: a voltage source; a device under test having a power input in operable communication with the noise introduction apparatus; and a noise introduction apparatus interposed between the power source and device under test in operable communication with the voltage source, the noise introduction apparatus comprising, a switching device configured to provide a low impedance conductive path when commanded, and a current limiting device in series with the switching device, the current limiting device configured to provide a low impedance conductivity for a selected current and a selected duration. The switching device and current limiting device cooperate to shunt the voltage source to the power input.

摘要： An input/output cable port assembly and electromagnetic interference attenuation method are provided. The cable port assembly includes a cable port structure mounted to an electronics rack with an opening for input/output cables to pass therethrough, and multiple bottom ferrite inductor portions and multiple top ferrite inductor portions. The bottom and top ferrite inductor portions include first and second surfaces, respectively. The inductor portions are configured to be stacked within the cable port structure with their first and second surfaces in opposing relation to define at least one ferrite inductor with a central opening defined by the first and second surfaces for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state current on the cable(s) passing therethrough.

摘要： An input/output cable port assembly and electromagnetic interference (EMI) attenuation method are provided. The port assembly includes a cable port structure for an electronics rack with an opening for input/output cables to pass therethrough, and a first and a second partition. The first and second partitions couple to the cable port structure and reside within the opening. The first partition includes at least one ferrite inductor portion and the second partition includes at least one second ferrite inductor portion. The partitions are configured to be disposed adjacent to each other as adjoining partitions within the cable port structure, and when disposed as adjoining partitions, the first and second ferrite inductor portions mate and define a ferrite inductor with a central opening for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state currents on the cable(s) passing therethrough.
