"They always get the job done"
I’ve been using Yokogawa Test&Measurement instruments for power measurement and analysis for several years and they always get the job done. They provide extensive and thorough documentation for their equipment and their drivers are very handy. Features like screengrabs of test results for easier sharing and the remote interface (which minimizes the time we spend having to automate tests) have proven to be incredibly helpful. My team needs instruments that are well documented, easy to use, and reliable. Yokogawa instruments check all these boxes.

Overview:
Yokogawa developed the PX8000 precision power scope, a high-accuracy power meter, which can measure reactor losses in inverters, motors and the like, by analyzing waveforms. The major specifications of the instrument are as follows: basic accuracy is 0.2%, voltage measurement bandwidth is DC and 0.1 Hz to 20 MHz (-3dB, typical), and current measurement bandwidth is DC and 0.1 Hz to 10 MHz (-3dB, typical). The PX8000 offers the functionality usually provided by a waveform measuring instrument, such as a variety of triggers, tracking, statistical processing, and waveform parameter calculation functions. Furthermore, to improve measurement accuracy at low power ratios this product comes with a de-skew function for correcting signal delays from the current sensor and a data latency adjustment function. This paper describes the PX8000, focusing on a newly developed element dedicated for power measurement and technology for phase correction.

We have added a harmonics current/flicker measuring function to the WT3000 Precision Power Analyzer with world-leading accuracy of power measurement. We have also created PC software for harmonics current/flicker measurement. This PC software and the WT3000 comply with the IEC61000- 3-2 harmonics current standard and IEC61000-3-3 voltage fluctuation/flicker standard, thus enabling the electrical power, harmonics current and flicker of electrical equipment to be measured precisely with a single unit. This paper outlines the harmonics current standard and voltage change/flicker standard, along with the measurement principle and PC-based software of the WT3000.
Overview:
The right tool to measure power in complex EV systems is a purpose-built power analyzer that captures three core parameters—voltage, current and power—as well as a few very important additional parameters (depending on what system you are testing) that contribute to understanding the efficiency and overall system performance.

Overview:
When I started with my company almost 20 years ago, Yokogawa Test&Measurement instruments were already in use and the engineers had no intention of switching. In fact, we still routinely use some of the older instruments because, well, they just work! The equipment doesn't really become obsolete, and they support their instruments as long as is feasible, which ultimately saves us money. Even so, as things change in our industry Yokogawa adjusts to meet those changes. From our sales representative through technical support and more, I can count on the Yokogawa team to really listen and work with us to provide a specific solution for unique problems.

Overview:
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.
