PRODUCT SHOWCASE 16-bit HD mode now standard for Rohde & Schwarz RTE, RTO and RTP ’scopes Starting immediately, all Rohde & Schwarz RTO and R&S RTP oscilloscopes are delivered with the high definition mode featuring 16-bit vertical resolution. Users benefit from more measurement performance at the same price. Higher-resolution waveforms enable more precise analysis of signal details that would otherwise be hidden by noise. The high definition mode increases the vertical resolution up to 16-bit. In power electronics, it is frequently the smallest details of a signal that are of interest, also for high amplitude signals, ie, when characterising switching power supplies. A high vertical resolution is necessary to measure small details of a signal with an amplitude up to several hundred volts. Rohde & Schwarz oscilloscopes accomplish this with a hardware lowpass filter that filters the signal after the A/D converter. The filter reduces the noise power, effectively increasing the signal-to-noise ratio and increases the resolution up to 16-bit. The bandwidth of the lowpass filter can be variably adjusted from 10kHz to a maximum of 2GHz to match the characteristics of the applied signal. The lower the filter bandwidth, the more the signal-to-noise ratio is improved. Waveforms are displayed in a higher resolution, showing signal details that would otherwise be hidden by noise. Thanks to the low-noise frontend and highly accurate single-core A/D converter, Rohde & Schwarz oscilloscopes have an excellent dynamic range and measurement accuracy. Since hardware lowpass filtering takes place in real time, acquisition and processing rates remain high and the measurement results are available quickly. All analysis tools, including automatic measurements, FFT and the history mode, can be used in high definition mode. High definition mode makes even the smallest signal details visible. The highly sensitive Rohde & Schwarz digital trigger system allows users to easily isolate these details and investigate them in greater detail. Scientists at The Australian National University (ANU) have made a fresh series of breakthroughs that could help further revolutionise solar technology – making it more efficient, and more accessible – following major discoveries last year. The team from ANU have been concentrating on the solar cell’s skin layer, which is 1000 times thinner than a human hair, and is used to conduct electricity and protect the solar cell. Previously, much of the research in this field has focused on improving the body of the cells. Lead researcher Dr Hieu Nguyen said when hydrogen atoms are injected into a solar cell’s skin, rather than the cell body, the performance of the entire structure is boosted significantly. The ANU researchers initially discovered the skin layer can emit light with some very distinct qualities. They quickly realised the presence of hydrogen atoms dramatically changes the characteristics of Contact: this light – informa- ANU College of Engineering and tion that can then be Computer Science used to understand East Road, Acton, Canberra 2601 what’s going on in- Tel: 0424 711 703 side the skin.

This means the oscilloscopes are able to trigger on even the smallest signal amplitudes. There are no unexpected aliasing effects in high definition mode. Since high definition mode is not based on decimation, the increase in resolution is not accompanied by a reduction in the sampling rate. When high definition mode is switched on, the full sampling rate can be used, ensuring the best possible time resolution. Mouser Electronics, Inc, in collaboration with Molex has a fascinating new eBook, “Welcoming the Connected Home”. In the new eBook, subject matter experts examine upcoming and future trends in home automation and strategies for designing Internet of Things (IoT)-enabled devices, as well as specific smart home solutions from Molex. From connected devices like light bulbs and appliances to security systems and home assistants, the smart home is allowing residents to interact with and program their living spaces to predict and react to their needs. The new eBook covers topics related to the connected home, exploring both current strategies as well as future possibilities. It includes tips on how to connect devices to the IoT, an exploration of upcoming capabilities in intelligent integration, and a survey of Molex products designed to serve specific smart home applications. Molex products help engineers design intelligent and integrated smart home systems which support a wide range of home automation applications including antennas, wire-to-wire connectors, cable assemblies, capacitive switches, LED dis- To read the ebook, visit: plays, and USB type-C www.mouser.com/news/ molex-ebook-2019/mobile/index.html connectors.
