Spectracom is a global manufacturer of precision time and frequency instruments and network-centric equipment used in a wide range of industries. Spectracom was founded in Rochester, New York USA in 1972. Its first product was a WWVB Receiver-Comparator, an instrument used to calibrate oscillators with traceability to national standards. Other early products included WWVB frequency and time standards which offered atomic clock accuracy at a fraction of the cost. This led to widespread use of these products in vital communications networks such as two-way police radio simulcast systems and master clocks for accurate time stamping of data and events within emergency call centers such as 9-1-1 public safety answering points. When GPS signals became publicly available in the 1990s, Spectracom offered its time and frequency products with embedded GPS receivers. These products are known by the registered trademarks Ageless and NetClock, the second being a popular brand of network time servers and master clocks. In 2005 Spectracom acquired the KSI line of bus-level timing products. These plug-in computer or instrument chassis cards provide precise timing within dedicated applications using GPS or IRIG timecode. In 2007 Spectracom was acquired by the Orolia Group and today operates as part of its Timing, Test & Measurement group.〔Orolia history from company web site: http://www.orolia.com/us_historique.php〕 The Spectracom brand has been applied to other Orolia acquisitions: Temex Sync, France (2007),〔ThomasNet News: http://news.thomasnet.com/companystory/529261〕 Rapco Electronics, UK (2008),〔Euronext News: http://www.euronext.com/trader/companynews/companyNews-4380-EN-FR0010501015.html?selectedMep=1&page=2&docid=647121〕 and Pendulum Instruments, Sweden (2009).〔Euronext News: http://www.euronext.com/trader/companynews/companyNews-4380-EN-FR0010501015.html?selectedMep=1&docid=773572〕 Facilities in all these locations continue to operate as units of the global Spectracom brand and cross-sell each other’s products and capabilities into their local and global markets. ==Notes== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spectracom」の詳細全文を読む スポンサード リンク
