Yokogawa Measurement Co., Ltd. is pleased to announce that it has developed the DLM3000HD series of compact high-resolution oscilloscopes with frequency bands of 500 MHz and 350 MHz, which will be released today. The new oscilloscope series has been expanded to a high-performance version of the DLM3000 series, providing higher resolution, more accurate waveform analysis, and more user-friendly and easy to configure features.

1.Developme.nt background

The DLM2000 series and its successor, the DLM3000 series released in 2018, are compact vertical oscilloscopes with four analog input channels. It has been widely used as a measuring instrument for daily use.

In recent years, in order to achieve a decarbonized society, clean energy related products such as motors, inverter equipment, and solar power generation equipment in the transportation sector need to be further energy-efficient. Especially, with the commercialization and mass production of next-generation power devices using silicon carbide (SiC), the demand for high-precision measurements in the power electronics industry using these devices continues to grow.

To meet these requirements, we have developed the DLM3000HD series, expanding our oscilloscope product lineup. This series improves vertical axis resolution and supports high channel measurements.

2.Product Features

The DLM3000HD series includes two models: the "DLM3054HD" in the 500 MHz frequency band and the "DLM3034HD" in the 350 MHz frequency band. The main functions include:

 Increase vertical resolution by 16 times

The vertical resolution of the DLM3000HD series is 12 bits, which is 16 times higher than the existing DLM3000 and enables more accurate waveform observation. Especially, developers of next-generation inverter devices have the advantage of being able to accurately observe small changes in high-speed signals, such as switches. This allows you to detect waveform overshoot, ringing, and other phenomena that can cause hidden and invisible unexpected issues

Analysis of Extended Serial Bus

Our oscilloscope's ability to automatically set the bus bit rate and voltage level during serial bus analysis has been extended to include waveform data acquisition. Therefore, it can adapt to infrequently occurring signals for automatic settings, thereby improving the efficiency of vehicle bus development and evaluation work.

Improve the efficiency of analysis work

Equipped with 1G (gigabit) sampling point memory, which is twice that of traditional products. Therefore, up to 200000 waveforms (twice the same ratio) can be stored as historical waveforms . In addition to doubling the number of searchable and organized waveforms, a single unit can also cover the behavior of braking devices that require capture at a fast sampling rate (up to 2.5 GS/s (gigabit samples per second)) for a few milliseconds, thereby improving the efficiency of evaluation and analysis tasks.

In addition, the dual unit synchronous measurement (DLMsync) function can achieve further multi-channel operation, by synchronously connecting two units, up to 8 analog channels can be measured simultaneously. For example, it is possible to check the operation of many power on sequences of electronic control units and debug equipment.
