Seica will be revealing two power semicondctor testers at PCIM in Nurember next month: one for ac and dc characteristics, and the other for thermal resistance. S20 IS3 (right) is intended to work with SiC and GaN  as well as more conventional technologies, and is for ac and dc, static and dynamic testing. “It performs accurate and repeatable characterisation of ...

Red Pitaya has upgraded its Stemlab 125-14 four-channel 60Mz software-defined test instrument. “This next-generation series enhances performance and reliability while maintaining backward compatibility,” according to the company. “With improved features such as enhanced RF input performance, USB-C connectivity, and a compact design, the Gen 2 series is designed to facilitate signal acquisition, generation and processing, whether used in educational settings, ...

The range of load cells and strain gauges available from Charcroft Electronics has increased with the acquisition of Sensor Techniques. Charcroft is a privately-owned,  distributor and manufacturer of electronic components, including passive, interconnect, electromechanical and optoelectronic components, load cells and strain gauges, power supplies and rugged semiconductors. Sensor Techniques is a distributor of load cells and strain gauges for use ...

Increasing dependence on wireless devices highlights the need for comprehensive RF radiation emission level testing, says Jon Kenny. As dependence on wireless devices that emit RF radiation continues to grow, so do the complexities of those devices and their international regulatory requirements. Specific absorption rate (SAR) testing plays a crucial role in assessing and ensuring the safety of such electronic ...

Remote patient monitoring is undergoing radical transformation while improving patient outcomes. Oriana Di Marco describes a wearable skin patch development case study. Telemedicine brings a radical transformation, making healthcare effective and more accessible to everyone. Advances in semiconductor technologies are playing a key role in the digital transformation of healthcare, enabling the design of a variety of wearables, smaller portable ...

Improved integration with the latest generation of automotive microcontrollers are amongst updates in the latest version of PLS’ Universal Debug Engine, to be called ‘UDE 2025’. “UDE 2025 comes with a new home screen,” said the company. “Immediately after starting the program, users now have direct access to their most recently used debugger workspaces, sorted by time. Creating a new ...

Yokogawa has created a differential probe with 400MHz 3dB bandwidth and a maximum input voltage of ±2kV. “Applications for, and production of, next-generation power devices utilising silicon-carbide technology necessitates ultra-precise measurement of high-voltage and higher speed signals,” according to the company. PBDH0400 is the name, and 702922 is the part number. Due to its interface connector and power supply, it can ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the vector network analyser for an oscilloscope. It is based on the company’s RTP084 scope, equipped with the wide-band modulated load-pull option (RTP-K98) and paired with its SMW200A vector signal ...

Bluetest and Rohde & Schwarz have created a MIMO stress testing perform for IEEE 802.11be  (Wi-Fi 7) equipment. It consists of R&S one-box CMX500 signaling tester (right), a Bluetest RF reverberation chamber – its RTS65, for example (below left), and Bluetest’s Flow control software. “In contrast to anechoic test chambers, reverberation chambers extensively reflect an RF signal inside the chamber, ...

Vehicle-to-Everything may be the technology answer to the continuous automotive trend to access digital services and third party and OEM applications, says Holger Rosier. Vehicle-to-Everything (V2X) devices serve as an interface to the digital world and offer the capability to provide software and firmware updates over the air, to offer real-time traffic information to the driver, to serve infotainment and ...
