"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.

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.
