An electrical conductor warms up when it conveys current. If the heat is high enough the conductor can be damaged, so it is beneficial to limit current flow. Three-phase electrical distribution systems are highly effective in limiting current flow without reducing the amount of power delivered to the load. They do this by separating phases […]
Radio comm test station, mobile smartphone form-factor test device complete 5G SA connection testing
5G Standalone (SA) connection testing has successfully taken place between Anritsu’s Radio Communication Test Station MT8000A and a mobile smartphone form-factor test device from Qualcomm Technologies, Inc., a subsidiary of Qualcomm Inc. The tests included Anritsu’s 5G modem and antenna modules with integrated RF transceiver, RF front-end and antenna elements. This latest milestone follows previous […]
Safety guidelines for hipot testing and setting up a safe testing area
A few simple steps ensure testing takes place safely when potentially lethal voltages and currents are involved in the testing process. Kevin Clark, Vitrek Inc. Hipot testing has long been a standard procedure for assuring the electrical safety compliance of electronic equipment. Early commercial hipot testers were actually not much more than a variac-driven step-up […]
User review: the new Tektronix AFG31000 Series arbitrary function generators
In the consumer electronics boom following World War Two, a rapidly-growing number of homes contained analog CRT-based TVs, and repair shops soon appeared on every street. Technicians found these complex devices could best be serviced by injecting a synthesized signal at various points and accessing it downstream by means of an oscilloscope, thus isolating the […]
Oscilloscope technology – What lies ahead?
Oscilloscope technology advanced rapidly from its early 19th Century roots through the triggered sweep and digital/flat-screen transformation in the 1980s. The trend has accelerated. Bandwidth and sampling rates have expanded exponentially. Additionally, new features and measuring and display capabilities have emerged. In this context, one wonders what lies ahead. The major oscilloscope manufacturers maintain robust […]
Understanding and testing asynchronous logic
Traditionally, computer and instrumentation engineers work with synchronous logic, where a global clock circuit imposes a timing structure to which all circuits down to the components level adhere. In synchronous logic, an autonomous oscillator outputs a square wave that never varies in frequency or amplitude. At the rising edge (sometimes falling edge) a potentially vast […]
MIPI C-PHY/D-PHY analyzer supports mobile display, camera, ADAS development
The new Envision X84 protocol analyzer is designed to ease troubleshooting and support the development of complex imaging and detection systems for mobile displays and cameras. Envision X84 is the industry’s first analyzer that supports both MIPI C-PHY/D-PHY and MIPI Camera Serial Interface (CSI-2)/MIPI Display Serial Interface (DSI-2) in a single platform, providing device designers […]
