The common BIST loopback method is easy to setup and time-saving but can not promise an acceptable confidence level for current faster and faster high-speed devices. On the other hand, to fully measure jitter related specs with industry standard instruments will lead to excessive cost of test (e.g., capital investment, time-to-market, test time). This paper proposes one solution for at-speed jitter performance testing on ATE, which covers jitter histogram, random jitter/deterministic jitter separation and jitter spectrum decomposition (stardust). This solution has been implemented in production of real devices and the result shows its high accuracy and cost effectiveness.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128566409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed analysis of physical model can hardly get analytic solution, while some usual simplification of model will lead to the loss of physical meaning. First a helical coordinate system is proposed in this paper. A semi-analytical finite element method is applied to elastodynamics equation for the calculation of wavenumbers. The displacement, strain and stress vectors are obtained by tensor analysis. And the relationship among them is deduced. The result shows the disperse behavior of guided wave in helix wire, which is depended on lay angle. That is different from straight wire, which is owed to its particular helix geometry structure.","PeriodicalId":321964,"journal":{"name":"IEEE 2011 10th International Conference on Electronic Measurement & Instruments","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129094473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The infrared imaging system is designed based on virtual instrument. A Non-Uniformity Correction (NUC) is applied by using two-point linear correction algorithm. Meanwhile, in order to enhance the contrast, the author preprocesses the image with the liner gray stretch on the premise of NUC. Through the test of UL 01011 320×240 and the analysis of the data by the imaging system, the results show that: the system can provide the real-time imaging, non-uniformity correction and gay stretch successfully.
