美國Crystal Instruments
Crystal Instruments公司1996年成立于美國。他們專門設計及生產專業的動態信號分析儀及聲學與振動測試分析儀器。2007年首先推出全球首家的手持式動態信號分析儀CoCo-80，目標生產最高素質產品，在國際市場以最優惠價錢提供最優質的儀器。
現時Crystal Instruments代表辦事處遍布全世界，其中有名的用戶包括美國海軍、美國交通部、洛克西德.馬丁、美國航天局、加拿大國防、豐田、通用、福特、IBM、戴爾、等等。
另外，公司提供軟件包。利用這軟件，用戶可更方便快捷下載測量結果，將數據作后分析或以電腦操作控制測量。
公司擁有成熟的研發團隊，特別在振動控制器和動態信號分析儀方面取得了一系列重大成果。在計算機、電子技術、機電控制及其它相關工程領域具有豐富的經驗，在數據采集、實時控制及信號分析等領域擁有多項專利技術。
 Crystal Instruments (CI) is an engineering firm focused on data acquisition, dynamic signal analysis and measurement data management. With over ten years' experience creating embedded and DSP systems for structural testing, product evaluation, algorithm implementation and application software programming, CI's products and technology are in use today by many of the world's leading companies, industrial providers and government agencies.

In 2007, CI introduced CoCo-80, the first handheld data recorder, real-time dynamic signal analyzer and vibration data collector that matches the performance of high-end lab-quality instrumentation. With its extremely compact form factor, low-power and rugged design, the CoCo-80 is ideal for field use. CoCo-80 is equipped with 4, 8 or 16 input channels and can accurately measure and record both dynamic and static signals. The mass flash memory can record 8 channels of streaming signals simultaneously up to 102.4 kHz. The combination of the dedicated human interface on the CoCo-80 and the PC based computer interface make it versatile and easy to use.

CI also provides engineering services in hardware and software development. The CI team includes more than 40 product managers and engineers. Most have Masters Degrees in Computer Science, Electrical Engineering or other related engineering fields. Each of CI's key engineers has more then 10 years' engineering experience. CI's engineers hold a number of patents in the areas of data acquisition, real-time control and signal analysis.
