An integrated measurement system for every electromechanical application
Faced with complex integrated systems, engineers need a sophisticated, flexible measurement solution for R&D, validation, and troubleshooting. ScopeCorders meet this challenge with built-in analysis and recording functions in an all-in-one data acquisition solution.
Designed for engineering insights, Yokogawa Test&Measurement ScopeCorders are:
- Integrated: Automate your measurements and analysis by making menu selections - no programming required.
- Configurable: Simultaneously capture data from any of 20 different modules.
- High Fidelity: Trustworthy measurements even in the noisiest environments.

"I owe my career to T&M"
It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get.

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:
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:
It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get. —Kenneth Shoemaker, Automotive Industry Consultant/Owner at Panama Prototypes

Overview:
We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics

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.
