Teledyne LeCroy demonstrated the world’s first 100 GHz real-time oscilloscope on July 24, 2013 at the research facilities of Teledyne Scientific Company in Thousand Oaks, CA. In the demonstration, the prototype scope successfully acquired and displayed live signals at 100 GHz bandwidth. In addition, the Teledyne LeCroy and Teledyne Scientific also unveiled an indium phosphide (InP) chip, which is the first device in a new chip set planned for future generations of high-speed oscilloscopes.

During the demonstration (see video clip below), the injection signal was 100 GHz with a 240 GS/s sample rate (each sample was taken is approximately 4 ps apart). The company’s target applications include CEI-25/28, CEI-56, optical coherent modulation communication systems, defense and radar applications, emerging 10-32 Gb/s serial data technologies, 100GBASE-R Ethernet, SAS12, PCI Express Gen4, Thunderbolt, and next-generation USB.

Notable technology details include the use of LeCroy’s patented digital bandwidth interleaving (DBI) technology; a high frequency microwave front-end developed by Phase Matrix, a National Instruments Company; and three high-speed analog oscilloscope channels. DBI works by splitting the input signal into multiple frequencies which are downconverted to the bandwidth of the digitizing system. Then it acquires and digitizes each band, using DSP to re-assemble them and compensate for distortion.

新闻大意是说力科7.24在加州奥克斯展示了100G实时示波器的应用，还是采用DBI技术，值得一提的是这次的前端是Phase Matrix做的，不是他们自行研发。同时，力科也展示了InP芯片，准备用在下一代示波器上。目前100G的示波器用的应该是IBM 的8HP SiGe工艺，还不是InP。目前在示波器上采用InP工艺的只有Agilent一家。

Teledyne LeCroy，Teledyne科技的全资子公司，日前演示了世界上最快速的100GHz实时示波器，成功的在100GHz带宽进行了实时信号的采集和显示。这次演示的示波器性能已经大大超越了目前业内的其它仪器。高速数字示波器是开发高速数字网络系统的重要工具，是数字时代下快速发展的云计算等大数据行业的关键支撑。

“达到100GHz实时示波器性能是Teledyne LeCroy达到的众多里程碑之一。” Tom Reslewic，Teledyne环境和电子测量仪器的CEO说道。“这一成果将会揭示很多新现象，开启获得新发现的通道，为高速测量领域的大规模进步铺平道路。”

这次演示工作在Teledyne科学公司的研发机构进行，位于美国的加利福尼亚千橡市。Teledyne LeCroy和Teledyne科技同时于今天宣布他们已经完成了下一代磷化铟(InP)芯片的设计和联合开发工作。这款联合开发的芯片是下一代高速示波器的核心器件。Teledyne公司于2012年8月全资收购了LeCroy(力科公司)，旨在于协同开发下一代超高速示波器。

“我们非常高兴看到在收购Teledyne LeCroy不到一年之后就达到了100GHz实时示波器的里程碑”，Robert Mehrabian，Teledyne公司的董事长兼CEO说道。“在同一天发布新款磷化铟芯片，显示了与Teledyne科学技术专家的巨大成果，我们非常有信心将高性能示波器推向下一个高度。”

磷化铟是一种更高级的半导体制造工艺，能够组成比传统制造工艺更高速的器件。Teledyne是下一代磷化铟技术的领导厂商，而且已经拥有高级的设计和生产能力。
