Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.

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.
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.
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.
