The latest version of the Moog Test Controller is more compact than earlier models and meets the different needs of test lab managers without the use of additional hardware. Moog’s engineers have also designed the new controller with an EtherCat bus, which provides the flexibility to meet future developments and the adaptability for future testing […]
Gallery: Power electronics on display at the IEEE ECCE energy conversion congress
The IEEE’s ECCE 2022 event took place in Detroit recently and featured 856 peer-reviewed technical papers, 17 special sessions, and an exhibit expo. We toured the exhibits which were heavily oriented toward automotive power electronics. Here are some of the impressions we came away with as we walked the aisles. Automakers move toward IPM motors […]
Isolated scope optimized for high-voltage, fast-slew-rate signals
The Cleverscope CS548 Oscilloscope is a 2-kV dc isolated-channel oscilloscope designed to be used wherever isolation and high CMRR are needed. It improves on the previous and successful CS448 for power electronics and high side test measurements. The CS548 is an individually isolated-channel high CMRR oscilloscope with four channels that has been designed for measurements […]
High-speed digitizer cards perform on-board summation averaging
A new firmware option has been created by Spectrum Instrumentation that allows the company’s high-speed M5i.33xx series of PCIe high-speed digitizers cards to perform on-board summation averaging. Averaging is a useful tool for reducing unwanted signal noise, while at the same time improving measurement resolution, dynamic range and signal-to-noise ratio (SNR). The new option enables […]
What to look for during instrument calibration
When you send an instrument to a calibration lab, what do you expect to happen? The comprehensive definition of calibration is a verification of instrument specifications by measuring actual performance using external lab standards, normally instruments, which have better performance than the thing they’re measuring and which are traceable to the International System of Units […]
Multi-channel coherent microwave RF source hits 20 GHz
A new RF Microwave Generator, the DSG5000 Series, can generate up to 20-GHz carriers with high signal fidelity. These new generators are available with two, four, six, or eight independent RF channels packaged in a single 2U full width mainframe. The DSG5000 Series features impressive long term phase stability between channels of ±1 degree and […]
Single microLED diode provides all colors, eliminates need for RGB sub-pixels
A single microLED diode handles all colors in displays, moving away from the constraints of the RGB (red-green-blue) sub-pixel model that underpins all current commercial display technologies. Porotech’s innovation lies in its game-changing DynamicPixelTuning (DPT) technology. By using a new class of Gallium Nitride materials, DPT enables a single microLED chip to produce any visible […]
Dispelling Myths: Don’t believe it when they say you need a bipolar gate drive for eGaN FETs
Use of a negative gate drive can lead to a larger voltage drop during deadtime and severe losses. Andrea Gorgerino, EPC GaN devices have gone from initial R&D to mainstream designs over the last 15 years. Unfortunately there are many misunderstandings left-over from those early-stage developments or dead-end technology branches. One of the most pernicious […]
BERT supports PCI Express 6.0 base specification receiver test
The Signal Quality Analyzer-R MP1900A now supports the PCI Express 6.0 (PCIe 6.0) Base Specification Receiver Test (Rx Test) and has been further enhanced with an SKP function to filter SKP packets to support separate clock architecture (SRNS). As a result, one MP1900A supports PCIe 3.0 to PCIe 6.0 and can calibrate stressed test signals […]
AEC-Q100-qualified IC load switches feature low-leakage currents
Two new Automotive grade AEC-Q100 I Q Smart load switch ICs, the AEC-Q100-qualified GLF1111Q and GLF1200Q, are rated for a wide temperature range (Grade 1 -40 to +125°C). The GLF1111Q provides industry-leading, battery-saving leakage current (2nA, typ.). The GLF1200Q features a true reverse-current blocking, which prevents a backup power source from being discharged when an […]
