LabVIEW NXG aims to simplify time-consuming tasks in automated T&M apps
A new release of LabVIEW NXG is designed to simplify the most time-consuming tasks in automated test and automated measurement applications, from setting up and configuring systems to developing test and measurement code and creating web-ready applications. These enhancements help engineers meet challenging time-to-market requirements. “Since the initial launch of LabVIEW NXG in 2017, we’ve […]
RF menus in the Tektronix MDO3000 oscilloscope
Many oscilloscope users become adept at acquiring signals in the time domain and using Math>FFT in mixed domain oscilloscopes to display signals simultaneously in time and frequency domains. This is excellent for demonstrating the fundamental relationship between these different display modes, and the whole thing is user-friendly and intuitive. In a Tektronix MDO3000 oscilloscope, at […]
Modules let spectrum analyzers serve as I/Q sources within open-source GNU radio apps
GNU Radio modules for the BB60C and SM200A spectrum analyzers allow the analyzers to be used as I/Q sources from within GNU Radio, as blocks in a flowgraph, components of a hierarchical block, or called from a script. According to Roger Rush, lead developer on the project, “Signal Hound and GNU Radio share a software-based […]
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 […]
User review: the new Tektronix AFG3000 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 […]
Isolated high-voltage 4-channel 200-MHz oscilloscope handles SiC MOSFET apps
Improvements to the Cleverscope CS448 — an isolated high common-mode rejection ratio (CMRR) four-channel 200MHz 14-bit oscilloscope — let it measure high voltages – now up to 1,600 V – for fast slew-rate signals such as those in a full or three-phase power electronics switching bridge. Examples of challenging measurement tasks the CS448 can handle […]
