Renewable & Fossil Energies

Global warming has lead to a charge for more 'green' energy solutions, including renewable energy, which has a lesser degree of impact on the environment. Continued research has made renewable energy more affordable today. Wind energy, photovoltaics, ethanol fuel options are all types of desirable alternative energy sources, however, there is still a great deal of research to be done to maximize the cost-effectiveness of these options. Yokogawa, dedicated to protecting the global environment, is eager to support these channels for optimizing fuel efficiencies and support our customers who make it their priority to do so, as well. Our high quality, innovative measuring units can support your efforts in emerging markets.

    • Values and key features of Yokogawa’s DL850EV ScopeCorder
    • Capture high-speed transient events and long-run trends
    • Widely used in automotive, power electric, mechatronics

    The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.

    The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.

    The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.

    Product Overview



    A demonstration reading a 4 - 20 mA transducer into an analog channel on the Portable DL350 ScopeCorder.


    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.


    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.


    This video demonstrates how to test to an IEC standard (IEC 61000) using a Yokogawa Test&Measurement WT5000 Precision Power Analyzer and the harmonic flicker testing software. The software automates the process of judging if the device under test is compliant with the chosen standard and allows you to output the necessary test reports for your records.


    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.

    • Using the portable DL350 ScopeCorder Memory Recorder Mode Easy Setup
    • Combined with 16-channel thermocouple input
    • Record hours, days, or weeks of data

    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.



    While DC power measurements are relatively straight forward, AC power measurements that include distorted waveforms, varying power factors, and multiple phases can add complexity to an otherwise simple measurement. During this webinar, we cover multiple fundamentals of power measurement.
