This new way of doing business will drive companies to change the way they specify, acquire and dispose of test equipment and more importantly how they manage the overall cost envelope of those assets. Although commercial companies have always done business this way, not all the same strategies will work for the Aerospace industry because of their unique attributes of program development, production and support. This paper will explore a strategy of combining commercial best practices with industry specific needs. Specifically, it will combine the notion of developing a portfolio of financial equipment acquisition options (rent, lease, buy) with specific PLC (Product Life Cycle) needs and program business essentials of the defense industry.","PeriodicalId":110721,"journal":{"name":"2011 IEEE AUTOTESTCON","volume":"10 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117297362","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}

Current inspection technology depends on operator experience with various inspection standards and is further complicated in military field deployments where bench top capable inspection equipment does not lend itself to field installations. Military fiber endface inspection is currently very expertise driven and time consuming for avionic environments. Thus there is a need for automated, portable fiber optic inspection technology that is suitable for all skill levels, and is capable of field deployment and maintenance.

The paper specifically focuses on how software tools can help alleviate these issues and increase the benefits of using these new standards in Automatic Test System (ATS) related applications. The ATML standards provide a common exchange format for test data adhering to the Extensible Markup Language (XML) standard. ATML promises to provide interoperability between tools and multiple test platforms through the standardization of common test related data. The ATML standards have now been published through the IEEE Standards Coordinating Committee 20 (SCC20) committee and are beginning to exhibit considerable interest in the ATS community and are now a requirement on some new Department of Defense (DoD) ATS programs. Different aspects of ATML related tools shall be discussed such as ATML Development tools which assist in the generation of ATML compliant instance files, new ATS related tools which use ATML data in their applications and the modification of existing ATS tools to utilize ATML Data. This paper also examines the work in progress of a Small Business Innovative Research (SBIR) Naval Air Systems Command (NAVAIR) sponsored program to develop ATML and test diagram tools. Utilizing ATML standards without the benefit of tools can be a labor-intensive, error-prone process, and requires an intimate knowledge of the ATML and XML standards. Employing the ATML standards on ATS programs promises to significantly reduce costs and schedule; the use of software tools are a key component in the success of these implementations and will help promote the use of ATML throughout the test industry.","PeriodicalId":110721,"journal":{"name":"2011 IEEE AUTOTESTCON","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123787199","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}

Many times the input to ADC in an application is other than standard signals such as sine wave or triangular wave. Parameters of ADC determined using dynamic testing with standard signals are not useful if input signals are different. Different sinusoidal components of application input can be determined by spectrum analyzer. Application input can be generated by downloading data points created by computer in an Arbitrary Waveform Generator (AWG). Differential Nonlinearity (DNL) of an ADC is determined using deviation of actual histogram from reference or ideal histogram. Further estimation of Integral Nonlinearity (INL) is done from summation of DNL. ENOB is determined by estimating ideal rms error and actual rms error. These rms errors are computed by taking difference of sampled ADC input value available in computer and corresponding ADC output. Simulation results for 5 and 8 bit ADCs are reported and experimental results for an actual 8 bit ADC are also reported.. Comparison of simulation results by proposed method is done for standard sine wave, triangular wave and application inputs. It is expected that this work will initiate research toward ADC testing using application input.","PeriodicalId":110721,"journal":{"name":"2011 IEEE AUTOTESTCON","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121768542","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 typical problem test engineers face is how to translate the final radio operating environment into a test plan. The typical approach would be to interpret the design parameters (assuming they were driven by the end user environment) and somehow derive tests to prove out a particular parameter. This is often accomplished through an assemblage of test equipment, each focusing on a specific operational parameter. This paper will discuss an approach that builds upon modern software-based Radio Frequency (RF) environment simulation tools in combination with a channel simulator in order to build the test channel. The advantages of this approach can be a flexible, reconfigurable test system that has clear traceability to the end user environment. This technique can be particularly advantageous when testing radios such as Software Defined Radios (SDRs) that support multiple modulation formats. Examples will highlight utilizing the same hardware for two different test channels; the first space-based, the second terrestrial.","PeriodicalId":110721,"journal":{"name":"2011 IEEE AUTOTESTCON","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121258746","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}
