This report describes a method of semiconductor resistance measurement using controlled energy levels and a digital processing oscilloscope to acquire and process test data.
This report describes basic methods, typical results, limitations, and technical variables which may provide some relative performance expectations for different lots of the same material, or comparison characteristics for different materials. This testing alone does not assure satisfactory operation in the engine, i.e., there is not a direct relationship to actual engine performance.
This specification establishes the performance, qualification, acceptance limits, and identification for aeronautical engine high tension spark igniters.
