Yokogawa Test & Measurement Corporation announces the release of its DLM3000HD series high-definition oscilloscopes supported by new IS8002CDV Classic Data Viewer (CDV) software. The compact and lightweight multichannel DLM3000HD meets market demand for high-precision, high-speed measurement of complex digital waveforms during inverter/motor development and testing. With a lineup spanning 500 MHz and 350 MHz frequency bandwidth models, the combination of proprietary low-noise detection and high resolution allows technicians to perform studies in minute detail, faster than before.
Development Background
Building on the existing DLM3000 mixedsignal oscilloscope series launched in 2018, Yokogawa applied its 100+ years of expertise and innovation in measuring instrument technology to develop the DLM3000HD. 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 requirement for more energy-efficient and sustainable motors and inverters. Adopting the DLM3000HD 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 silicon-carbide (SiC) technology, which can switch on and off in a few nanoseconds. Oscilloscopes offering bandwidths of 350 MHz or greater are necessary 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 the series steps up to the challenge of performing high-precision parameter measurements, statistical analysis, and real-time mathematical functions.
Features
In comparison with the existing DLM3000, resolution some 16 times greater (12 bit) in the vertical axis captures waveform overshoot and ringing for more accurate observation of tiny changes in high-speed signals. A long 1 Gpoint memory (double the 0.5 Gpoint memory of the DLM3000) supports the development and evaluation of next-generation inverter devices by recording multiple channels simultaneously, greatly increasing work efficiency. Engineers can make accurate observations of subtle changes in measurement target signals over a long period of time (even at high sample rates up to 2.5 GS/s), confirm signal waveforms, and detect signals causing unexpected anomalies.
Another unique feature of the DLM3000HD series is the pioneering auto set-up function for in-vehicle serial bus development and evaluation, a capability that is also possible during post data acquisition analysis. This time-saving function, which automatically configures the optimal bit rate and threshold level, accelerates the delivery of secure, reliable measurement results in the automotive industry.
