Though the advantage of linear amplifications is faithful reproduction of the (synthesized) oscillator waveforms, various harmonics injected on individual phases (Line to Neutral) may not produce the expected results when observed Line to Line.
Testing and validating new technology libraries and sophisticated devices has become an increasing challenge as the need for more advanced and complex radiation-hardened semiconductors rises. And diagnosing Single Event Effects (SEEs) can present further dilemmas, especially when Boeing went to test its Radiation Hardened by Design technology on the IBM 90nm process. To the rescue: DAFCA, which provided embedded instrumentation to help in real-time observation and analysis of previously inaccessible device confines.
The COM Express™ Carrier Design Guide: Guidelines for designing COM Express™ Carrier Boards, March 13, 2009 (Rev. 1.0) is a design guide and not a specification. It contains additional detail information but does not replace the PICMG COM Express™ (COM.0) specification.
