Yokogawa Test&Measurement Released DLM3000HD Series Compact High-Definition Oscilloscopes

06/08/2026

Yokogawa Test & Measurement Corporation announced the release of the DLM3000HD series of compact, high-definition oscilloscopes. Positioned as a high-performance version of the DLM3000 series, the DLM3000HD series expands Yokogawa’s oscilloscope lineup with 500 MHz and 350 MHz frequency bandwidth models that deliver higher resolution for more accurate waveform analysis, and come with features that improve usability and enable easier setup.

Yokogawa’s DLM2000 series of compact four-channel mixed signal oscilloscopes released in 2008 and the successor DLM3000 series launched in 2018 have proven popular for general use with developers of electronic and mechatronic devices. However, given the growing emphasis in recent years on measures that will help to decarbonize society, there is a need to increase the energy efficiency of motors and inverters used in the transportation sector and clean energy-related products such as solar power generation devices. This need is particularly acute in the power electronics industry, where the increase in applications for and production of next-generation power devices utilizing silicon-carbide (SiC) technology is driving the requirement for ever greater measurement precision. With its support of multi-channel measurement and its improved resolution on the vertical axis, the DLM3000HD series meets these needs.

Main Features

The DLM3000HD series consists of two models: the 500 MHz DLM3054HD and 350 MHz DLM3034HD.

1. 16 times higher vertical resolution
   The DLM3000HD series offers 12-bit vertical resolution that is 16 times higher than that of the existing DLM3000 series for greater accuracy in waveform observation. This is particularly beneficial for developers of next-generation inverters, enabling the accurate observation of minute changes in high-speed signals, such as during switching. This allows the detection of phenomena that can cause unexpected anomalies, including waveform overshoot and ringing.
2. Enhanced serial bus analysis auto-setup function
   Another useful feature of the DLM3000HD series is that the time-saving serial bus analysis auto-setup function, which automatically sets the optimal bit rate and threshold level, can now also be used with previously captured waveforms. This means that auto-setup can even be used for low-frequency signals, improving the efficiency of in-vehicle bus development and evaluation work.
3. Improved analysis efficiency
   The DLM3000HD series is able to store up to 1 billion points of acquired data, which is twice that of the DLM3000 series. This allows users to store history data on up to 200,000 captured waveforms as history waveforms*. In addition to doubling the number of waveforms that can be searched and compared using the long memory, this means a single device can measure the behavior of braking systems and other apparatuses that needs to be captured at a high sampling rate (up to 2.5 GS/s) for several milliseconds, improving the efficiency of evaluation and analysis work.
