Supporting the development of the next generation of power electronics for automotive and other applications
Yokogawa Test & Measurement Corporation announces the launch of the DLM5000HD series of high-resolution oscilloscopes. Positioned as a high-performance device, even more so than those already known from the DLM5000 series; expanding solutions for 350 and 500 MHz, offering greater resolution for more precise waveform analysis and with improvements in usability and ease of configuration.
DLM5000HD Series High Resolution Oscilloscope
Background
The 8-channel mixed oscilloscope series DLM4000 launched in 2012 and its successor the DLM5000 series launched in 2020 have been very popular for electronics and mechatronics developers recently. However, given the importance in current years on measures that will help decarbonization, there is a growing need to develop more energy-efficient motors, inverters, and products related to clean energy, such as solar energy generation devices. This need is most acute in the power electronics industry, where increasing applications for next-generation power devices based on silicon carbide (SiC) technology drive the need for even more precise measurements. With its multi-channel measurements and improved vertical resolution, the DLM5000HD series more than meets these needs.
Key features
The DLM5000HD series consists of 2 8-channel models (500 MHz DLM5058HD and 350 MHz DLM5058HD) and 2 4-channel models (500 MHz DLM5054HD and 350 MHz DLM5034HD).
The DLM5000HD series offers 12-bit vertical resolution that is 16 times higher than the current DLM5000 series, for greater accuracy in waveform display.
This is particularly beneficial for developers of next-generation inverters, accurately enabling the observation of high-speed signal changes. This allows the detection of phenomena that may cause unexpected anomalies.
Another useful feature of the DLM5000HD series is the time-saving serial bus analysis auto setup function, which automatically assigns the optimal sampling rate and threshold level, and can be used with previously captured waveforms. This means that auto setup can even be used on low frequency signals, improving the efficiency of in-vehicle bus development and evaluation work.
The DLM5000HD series can save up to 1 GP of acquired data, twice that of the DLM5000 series. This allows the user to save historical data up to 200,000 waveforms as historical data. Furthermore, doubling the number of waveforms that can be searched and compared using this memory means that a single device can measure the behavior of braking systems and other devices that need to be captured at large sampling rates for several milliseconds, improving evaluation efficiency. and analysis work.
As with the DLM5000 series, measurements can be captured with up to 16 analog channels and 64 logical bits (8 8-bit channels) using the dual sync DLMsync option to drive two 8-channel units. This simultaneously allows both analog and logical measurements to, for example, analyze boot sequences while debugging a control unit.
* Waveforms are automatically saved in internal memory.
