18 INDUSTRY NEWS Issue 1 2021 Power Electronics Europe www.power-mag.com “With the DL950, the ScopeCorder family attains new levels of data acquisition speed and greatly improved usability”, says Terry Marrinan, Yokogawa Test & Measurement’s Vice President for Europe & South East Asia. “Offering the versatility to discover more from a large number of input types, the insight available from a high bit resolution and a high level usability from easy set-up, the DL950 gives developers the tools they need to gain detailed information on the behavior of energy efficient and new renewable energy technologies and devices.” The new ScopeCorder is inteded for many markets, including transportation for applications such as testing electric vehicles and also associated SiC/GaN inverters. For power and harmonics analysis the G05 option is available. Here a single DL950 can evaluate a system with battery-driven motors, such as an EV. The DL950 calculates the conversion efficiency from the input and output power of the inverter and analyzes the effects of harmonics caused by external disturbances while capturing mechanical variations in motor speed and torque. Uses in the power and energy sector include capturing data on renewable energy systems, while in industrial equipment it can be used for testing high efficiency motors, robots and sensors (Figure 1). Oscilloscope and recorder with large touch screen The DL950 is easy to use via a large 12.1 inch touch screen, providing convenient access to its features. Yokogawa’s power analyzers and a selection of other instruments can be time synchronized through the device’s integrated IEEE1588 PTP master function and the IS8000 Integrated Software Platform. The units can also be controlled remotely, allowing home workers to continue conducting tests while working away from the test laboratory. Dedicated application menus simplify the setup. Touching an application icon brings up the graphical setup screen for the application, while users can also register frequently used applications as favorites. Providing a combination of high-speed sampling and signal fidelity of an oscilloscope and the long- term data recording capabilities of a recorder, the DL950 measures signals at a high bit resolution while securing data in harsh environments. Building on the capabilities of the DL850E, the new DL950 ScopeCorder can handle larger amounts of data at a faster sample rate and with a longer recording time. It has a large acquisition memory up to 8 Gpoint, and a 200 MS/s sample rate at 14-bit, compared to the DL850E’s 100 MS/s at 12-bit. Up to 32 isolated analog channels with 10 MS/s at 16-bit or up to 128 digital Yokogawa Launches NextGen ScopeCorder Yokogawa Test & Measurement has added in March another new instrument to its ScopeCorder family of portable multi-channel data-acquisition recorders, extending and improving their speed, channel count and data acquisition features. The DL950 is designed to offer a highly detailed view of an application’s electrical and mechanical behavior.
