Abstract:
1. 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 communication with a noise introduction apparatus; said noise introduction apparatus interposed between the power source and device under test in communication with said 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 said switching device, said current limiting device configured to provide a low impedance conductivity for a selected current and a selected duration; wherein said switching device and current limiting device cooperate to shunt said voltage source to said power input so as to selectively generate a current spike sufficient to facilitate evaluation of the susceptibility of the device under test to common mode noise, the device under test comprising computer sysplex including a plurality of processing complexes and coupling facilities.
