Yokogawa DLM300023 October 2018 - Yokogawa Test & Measurement launched the DLM3000 series of mixed signal oscilloscopes with models for the 200 MHz, 350 MHz, and 500 MHz bandwidths. The new series is a successor to the DLM2000 series of mixed signal oscilloscopes and comes with new functions that meet the needs of customers who are developing technologies for electric vehicles (EVs) and power electronics.

Released in 2008, Yokogawa’s DLM2000 series mid-range mixed signal oscilloscopes have proven popular with developers of power electronics, car electronics, and mechatronic devices. Yokogawa has improved on the DLM2000 by redesigning the hardware and adding functions that greatly improve performance:

Improved functionality

The models in the DLM3000 series support either two-channel or four-channel input. Even when simultaneously measuring input from every channel, each of these models can maintain a maximum sampling rate of 2.5 G/s (giga sampling/second), two times faster than the DLM2000 series.

With the improved hardware design, residual noise has been reduced 50%, the measurement sensitivity setting range has been extended to 500 μV, and the maximum input voltage has been extended to 300 Vrms. These features enable the DLM3000 to accurately observe signal waveforms over a wider voltage range.

The high-speed measurement of signals over longer periods of time generates a great volume of data. The DLM3000 supports the USB3.0 standard and thus is able to transfer large amounts of data at high speed for storage on a PC.

Improved operability

The DLM3000 user interface inherits many of the features that have been well received in other Yokogawa products, but now includes a capacitive touchscreen that offers the same intuitive ease of use found in modern smartphones.

Optional functions for EV development and debugging

To speed up the development of EVs and ADASs, the DLM3000 comes with a trigger function that supports the CAN with Flexible Data-Rate (CAN FD) and CXPI in-vehicle LAN standards. As both the waveform data captured with the trigger function and the signal analysis results can now be displayed on the same screen, users can identify at a glance the relationships between these two sets of data.

The DLM3000 also satisfies engineers’ need for more efficient debugging. The DLM3000 is able to store up to 500 M points of acquired data, which is twice that of the preceding Yokogawa oscilloscope series and more than any other mid-range mixed signal oscilloscope on the market today. With this function, the DLM3000 history function can retain up to 100,000 waveforms, twice that of the preceding series. The number of waveforms that can be searched and compared has thus been doubled, for improved efficiency in debugging. Furthermore, a 60 GB SSD can be installed for additional data storage capacity.
