Yokogawa releases high-speed data acquisition unit

Yokogawa Test & Measurement has announced the release of the SL2000 High-Speed Data Acquisition Unit, a ScopeCorder series product with a wide range of data logging functionalities for evaluation and test applications, including high-speed sampling and analysis. The SL2000 is a modular platform that combines the functions of a mixed signal oscilloscope and a data acquisition recorder, and is designed to capture fast signal transients and long-term trends. It is suitable for applications such as R&D, validation, and troubleshooting.

The SL2000 can be used separately or in combination with the DL950 ScopeCorder, depending on the application. With the ScopeCorder product family, Yokogawa provides a multifaceted, total solution for the high-precision mechatronics and electric power markets that is contributing to the advancement and development of new technologies and applications.

In the four years since the DL950 ScopeCorder was first brought to the market by Yokogawa, there have been many technical advances in the electric vehicle (EV), renewable energy, and other industrial fields. Today, there is an ever-greater requirement for the capability to simultaneously measure multiple parameters and for the systemisation of mechatronic measurements in product development. For example, in the development of motors for industrial and EV systems, one essential test for checking and improving a product is the durability test. This test takes a long time to complete and requires a highly reliable measuring instrument and high sampling rates.

The SL2000 performs long-duration multi-channel measurements while precisely analysing even the most detailed aspects of waveforms. With its dual capture function, the SL2000 can perform measurements over long periods of time at speeds of up to 200 MS/s. And in situations where post-processing is required on a PC following measurement, the main unit can continue to perform measurements and has a function that allows calculations to be performed in real time. This shrinks takt time – the calculated pace at which completed units must come off the production line.

By using the integrated measurement software IS8000, it is easier to perform the long-term measurements required for durability testing, helping to improve the efficiency of product design and evaluation work. In addition, isolation measurement technology ensures the noise resistance required for durability testing in harsh environments.

The SL2000 has eight available slots (with up to 32 channels), for which over 20 types of input modules are available to enable measurements of electrical signals, mechanical performance parameters indicated by sensors, and decoded vehicle serial bus signals. To increase the number of measurement channels, up to five SL2000 and DL950 units can be synchronised.

Major Target Markets
• Transportation (automotive, rail, aviation, etc.)
• Power and energy (renewable energy, smart cities/homes, data centres, etc.)
• Mechatronics, including industrial robots and motors

Integrated matching filters from ST now available for long-range wireless MCUs

STMicroelectronics has released a set of antenna-matching companion chips for STM32WL33 wireless microcontrollers (MCUs) to simplify the development of IoT, smart-metering, and remote-monitoring applications.

The new MLPF-WL-01D3/02D3/04D3 ICs combine impedance matching and harmonic filtering on a single glass substrate to optimise the main radio’s RF performance, leveraging proprietary integrated passive device (IPD) technology. Precision engineered and housed in an ultra-compact package, the highly integrated devices ensure right-first-time design while saving development time, bill-of-materials costs, and board space.

Integrating antenna protection, the new devices substantially simplify the RF connection to the MCU. In addition to ensuring optimal performance, integrated matching and filtering also increases reliability and reduces overall cost by eliminating the need to combine multiple discrete components.

In total, there will be seven variants, letting designers optimise for radio operation in high-band (826-958MHz) or low-band (413-479MHz), high-power (16dBm/20dBm) or low-power (10dBm), and for 4-layer or 2-layer PCB designs. The non-conductive glass substrate ensures outstanding performance with minimal temperature drift, and the chip-scale package has extremely compact dimensions, measuring just 1.47mm x 1.87mm and 630µm high after reflow.

The long-range sub-GHz radio of ST’s STM32WL33 wireless MCUs can operate in either of the 413-479MHz and 826-958MHz license-free bands and with up to 20dBm output power where local regulations permit. With an Arm® Cortex®-M0+ core and selected peripherals also on-chip, the highly integrated wireless MCUs simplify the design of remote-monitoring equipment for smart city, smart agriculture, and smart industry. Applications include smart meters, and safety systems, asset-trackers, and proximity detection. A set of reference designs (STDES-WL3xxxx), pre-certified and fine-tuned for STM32WL33 MCUs, is also available.

Rohm develops new compact surface-mount near-infrared LEDs

Rohm has expanded its portfolio of surface-mount near-infrared (NIR) LEDs with new compact top-view types. They are optimised for applications such as VR/AR devices, industrial optical sensors, and human detection sensors.

The demand for advanced sensing technologies utilising near-infrared (NIR) has grown in recent years, particularly in VR/AR equipment and biosensing devices. These technologies are used in applications such as eye tracking, iris recognition, and blood flow/oxygen saturation measurements that require high accuracy. At the same time, miniaturisation, energy efficiency, and design flexibility are becoming increasingly important. In industrial equipment, near-infrared LEDs are playing a greater role with the rise of precise printer control and automation systems. In response, Rohm is expanding customer options by developing a lineup of compact packages and wavelengths that offer greater design flexibility, while contributing to higher precision and power savings by achieving high radiant intensity.

The new lineup consists of six models in three package configurations, including two ultra-compact (1.0mm × 0.6mm), ultra-thin (t=0.2mm) products as part of the PICOLED series: SML-P14RW and SML-P14R3W. In addition, there are four variants in the industry-standard (1.6mm × 0.8mm) size, featuring a narrow beam circular lens package (CSL0902RT, CSL0902R3T) and flat lens design that emits light over a wide range (CSL1002RT, CSL1002R3T). Each package is available in two wavelengths, 850nm (860nm for the SML-P14RW) and 940nm, allowing customers various options for their specific application needs. The 850nm wavelength is ideal for phototransistors and camera sensors, making it suitable for high-sensitivity applications such as eye tracking and object detection in VR/AR. At the same time, the 940nm wavelength is less affected by sunlight and does not appear red when emitting light, making it suitable for motion sensors. It is also widely used in biosensing applications such as pulse oximeters to measure blood flow and oxygen saturation (SpO2).

The light source incorporates an NIR element with an optimised emission layer structure utilising proprietary technology developed through in-house manufacturing expertise. This has made it possible to achieve industry-leading radiant intensity in a compact package, which was previously considered difficult. For example, compared to a standard 1006 size product, the SML-P14RW delivers approx. 1.4 times the radiant intensity at the same current. In other words, the SML-P14RW consumes 30% less power to achieve the same radiation intensity. This technology improves sensing accuracy and power savings for the entire system.
