Yokogawa Test & Measurement recently released the DLM3000HD series of high-definition oscilloscopes, supported by the company's IS8002CDV Classic Data Viewer software. Addressing the market demand for high-precision, high-speed measurement of complex digital waveforms during inverter/motor development and testing, the compact and lightweight, multichannel DLM3000HD offers a lineup including 500- and 350-MHz bandwidth models.
The devices' proprietary low-noise detection and high resolution enable users to rapidly perform studies in minute detail. The IS8002CDV software accelerates tasks with rapid response times, swift analysis of measurement data, and advanced algorithms.
Answering the Call for a Lightweight, High-Precision Scope
The DLM3000HD rose as a response to demands from customers for a lightweight, compact oscilloscope with higher precision and rapid startup speed to support the need for more energy-efficient and sustainable motors and inverters. Its ability to capture highly accurate voltage and current waveforms with high sample rates targets electric motors and drives as well as next-generation power devices deploying wide-bandgap silicon-carbide (SiC) technology, which can switch on and off in a few nanoseconds.
Thanks to the oscilloscopes' multichannel measurement, wide bandwidth capabilities, and significantly improved vertical axis resolution, they can perform high-precision parameter measurements, statistical analysis, and real-time mathematical functions.
Compared to the legacy DLM3000, the resolution is up to 16X greater (12 bit) in the vertical axis to capture waveform overshoot and ringing for more accurate observation of tiny changes in high-speed signals.
A one-Gpoint memory supports the development and evaluation of next-generation inverter devices by recording multiple channels simultaneously, to make accurate observations of subtle changes in measurement target signals over a long period of time, even at sample rates up to 2.5 Gsamples/s. It also confirms signal waveforms and detects signals causing unexpected anomalies.
Automatic Setup for In-Vehicle Serial Bus Evaluation
A novel feature of the DLM3000HD series is its advanced auto setup function for in-vehicle serial bus development and evaluation, which can also be performed during post-data-acquisition analysis. It automatically configures the optimal bit rate and threshold level to accelerate secure, reliable measurement results, with four-channel synchronous measurement via the DLM3000HD.
An optional dual-unit synchronous measurement (DLMsync) function facilitates a unified system of eight channels by connecting two units. In addition, the DLM3000HD supports time synchronization with power analyzers and other waveform measuring devices for time-correlated measurements.
The oscilloscopes also offer high noise immunity for operation even in harsh environmental conditions. On top of that, it's possible to disable the touch panel and use only the buttons if absolutely necessary.
The IS8002CDV software has an updated UI and enables remote control without the need for any programming, with emulation of the instrument on the PC. This allows for operation as normal, with offline analysis of files that enables engineers and researchers to use the instrument for other measurement tasks.
