High-definition oscilloscopes and viewer software released

Yokogawa Test and Measurement Corporation has released its DLM3000HD series high-definition oscilloscopes supported by new IS8002CDV Classic Data Viewer (CDV) software. The compact and lightweight multi-channel DLM3000HD satisfies market demand for high-precision, high-speed measurement of complex digital waveforms during inverter/motor development and testing. With a lineup spanning 500MHz and 350MHz frequency bandwidth models, the combination of proprietary low-noise detection and high resolution allows technicians to perform studies in minute detail, faster than ever before. The new IS8002CDV software further supports expediency with its fast response times, swift analysis of measurement data, and advanced algorithms.

Building on the existing DLM3000 mixed-signal oscilloscope series launched in 2018, the company has applied its 100+ years of expertise and innovation in measuring instrument technology to develop the new series. The product stems from requests made by customers for a lightweight, compact oscilloscope with higher precision and rapid start-up speed that supports the ongoing necessity for more energy-efficient and sustainable motors and inverters. Adopting the series to capture highly accurate voltage and current waveforms with high sample rates addresses the capabilities of electric motors and drives to ensure efficiency in transportation sector applications, for example. Another development driver is next-generation power devices deploying SiC technology, which can switch on and off in a few nanoseconds. Oscilloscopes offering bandwidths of 350MHz or greater are essential to capture the fast rising and falling edges of the transient (high-intensity voltage spike during switching). Thanks to its multi-channel measurement, wide bandwidth capabilities and vastly improved vertical axis resolution compared with the existing-generation oscilloscope, the series steps up to the challenge of performing high-precision parameter measurements, statistical analysis, and real-time mathematical functions.

The vertical axis resolution is some 16 times greater (12 bits) than that of the existing DLM3000. This captures waveform overshoot and ringing for more accurate observation of tiny changes in high-speed signals.

With its updated UI, IS8002CDV software provides easy remote control without the necessity for any programming. There is no learning curve thanks to emulation of the instrument on the PC, permitting operation as normal. The offline analysis of files also lets engineers and researchers to use the instrument for other measurement tasks, increasing its utilisation.

Applications include:

Design and assessment of in-vehicle serial bus/network protocols, including CAN, CAN FD, and other in-vehicle standards; development and analysis of SiC/GaN inverters, EV chargers, UPS, and DC-DC converters; development of ECUs and embedded mechatronic devices; and analysis and testing of industrial devices like high-efficiency motors, robots, and sensors.
