示波记录仪

Yokogawa波形记录仪可捕捉高速瞬变、低速趋势或介于其间的任何信号。波形记录仪是灵活、强大的多通道测试和测量解决方案,将高精度示波器和传统有纸或电子波形记录仪的优点集于一身。

横河波形记录仪是一款功能强大的便携式数据采集录波仪,可以捕捉与谐波分析瞬态事件,显示长达200天的趋势波形。通过插拔模块,可以灵活组合电信号与物理信号(传感器信号,如CAN、LIN和串行总线)的测量,还能实现实时功率运算的触发。

让我们来感受世界一流的横河录波仪:自1988年首款机型面世以来,YOKOGAWA一直不断创新,致力于电力电子、机电一体化和新能源等前沿行业专用录波仪的研发,近期又推出全新DLM系列录波仪,既有面向低成本市场的4CH MSO示波器——DLM2000系列,也有业界唯一的全新8CH MSO波形记录仪

DL950示波记录仪可捕获并分析各种电子、物理传感器信号和串行总线。它是一个独特的组合,高采样率,可在长期记录的同时查看细节。

严苛的测量条件需要高性能与灵活的解决方案。这就是DL350示波记录仪的设计理念。 DL350与其它示波记录仪共用同样的18种插拔模块,电池供电使其易于携带,可在受限的空间中使用。

DL350最多提供8路模拟量和16路数字量通道,采样率可达100MS/s,最大绝缘电压1KV,最高分辨率16位,支持多种模块,可灵活配置,适用于各种长时间和瞬间变化波形的测量。

可充电电池的使用,不仅使得现场测试成为了可能,它与主电源配合,还起到了UPS的作用。

一款实实在在不打折扣的高性能数据采集单元,具有突出的快速数据采集、传输和存储功能。

IS8000软件平台是一套能加速工程流程的集成解决方案。它是一款高度集成了多台仪器时序、控制和数据采集的突破性软件,创建了一套可靠、高效和统一的全方位测量组件。

    Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.

    This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.

    In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.

    To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.

    概览:

    CAN Bus communication is widely used in the transportation industry where reliable transmission of data is paramount. Monitoring and recording these communications can be easier when using the proper instruments. In this video, a Yokogawa Test&Measurement Applications Engineer demonstrates how to setup the DL950 ScopeCorder to read the temperature of a motor drive alongside its voltage and current output.

    概览:

    The multi-unit synchronization option for the Yokogawa Test&Measurement DL950 ScopeCorder lets you time synchronize up to five DL950 ScopeCorders, for up to 160 channels of voltage, current, temperature, strain measurements, and more. This video walks you through how to set up and connect the multiple DL950 ScopeCorders, take measurements, and pull the data from all of the instruments for analysis with the IS8000 Integrated Test and Measurement Software Platform.

    概览:

    Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.

    The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.

    概览:

    Looking for a turnkey high-speed data transfer solution with better bandwidth and minimal manual overhead?

    The 10Gb Ethernet option on the Yokogawa Test&Measurement DL950 ScopeCorder fits that very role and makes capturing and recording high-speed data seamless and convenient.

    Record data at 50 times the speeds of traditional Ethernet and USB connections and automatically transfer data to your PC in a single step using the IS8000 Integrated Software Platform.
