Test gear speeds EMC tests under real driving conditions
New test gear supports automated testing with simulation of real driving conditions while covering typical automotive standards. The AVL PUMA 2 automation controls the test cycle and stores the measured data, in synchronization with the R&S ELEKTRA EMC test software to exchange information between the testbed and the EMC measurement equipment. The ELEKTRA software has […]
Why you don’t need a variable-speed drive to change a fan’s speed
To engineers schooled in modern motor control methods, it may be hard to grasp why three-speed fans designed to move air around in a room can be inexpensive. After all, these fans are powered by as motors, and the go-to method for changing the speed of industrial ac motors is via variable-frequency drives. VFDs work […]
5G LPWA ALT1350 chipset boasts ultra-low power consumption
The ALT1350 is the world’s first cellular LTE-M/NB-IoT solution to enable additional LPWA communication protocols, as well as satellite connectivity (NTN), in a single chipset, opening the door to further innovation in the connected world. The ALT1350 by Sony is the most advanced cellular IoT solution on the market, with an architecture that resolves IoT […]
Step attenuators feature attenuation accuracy of ±5 dB
New step attenuators feature attenuation accuracy of ±5 dB, making them candidates for high-reliability applications demanding accurate adjustment of attenuation values. Additional superior performance characteristics for the step attenuators include 1 dB maximum insertion loss and a maximum VSWR of 1.4:1. These high-reliability step attenuators offer wide coverage and high power with an operating frequency […]
Temperature-compensated RF amps cover 0.5 GHz to 40 GHz
A series of temperature-compensated amplifiers address precision performance and test-and-measurement applications. Fairview’s new series of coaxial packaged, temperature-compensated amplifiers covers broadband and ultra-broadband frequencies ranging from 0.5 GHz to 40 GHz. Designs incorporate pin diode attenuation circuitry that senses and adjusts broadband gain levels and maintains a minimum gain level of 35 dB over the […]
Researchers claim to beat dendrite battery blues
Dendrites are projections of metal that can build up on the surface of lithium anodes and penetrate into the battery electrolyte, eventually crossing from one electrode to the other and shorting out the battery cell. What gives rise to these metal filaments has been somewhat of a mystery, and there has been little progress on…
What’s a ring tester and why do you need one?
If you one day find yourself with a transformer that might or might not have a shorted winding, your first inclination for verifying your suspicions might be to find an inductance meter. The problem with powering up an inductance meter for this situation is that the inductance of a transformer containing a shorted turn might […]
APEC 2023 announces first-ever student job fair
The Applied Power Electronics Conference (APEC) will conduct its first-ever Student Job Fair on Tuesday, March 21, 2023, from 2:00 p.m. to 4:00 p.m. at the Orange County Convention Center in Orlando. The goal is to connect participating companies with top-quality, talented students who are already attending the conference and exhibition. The Student Job Fair […]
