PHY conformance test tool to support UWB development efforts
A FiRa-validated ultra-wideband (UWB) PHY Conformance Test Tool (PCTT) supports the further development of an open and standardized UWB ecosystem. With expertise and experience in wireless technology verification and certification, Rohde & Schwarz is well positioned to provide a test tool to support interoperability on the UWB physical layer as specified by FiRa. Thanks to […]
Scope-based diagnosis of three-phase motor drives
Ordinary oscilloscopes can view basic parameters in modern motor drives, but operational insights generally require specialized power analyzers. Variable frequency drives (VFD) generate carefully controlled pulse-width modulated (PWM) waveforms to modulate the speed of industrial ac motors. Often, the motors involved are three phase. Three-phase ac induction motors (ACIMs) are widely used though they are […]
EMI testing for IoT transceivers
A few oscilloscope measurements can give insight into sources of electromagnetic interference that garble the operation of wireless IoT devices. Examine a typical wireless device with an internet of things connection and you’ll likely find multiple RF receivers squeezed together in close proximity onto a circuit board. Cramped quarters characterize modern IoT electronics, so sensitive […]
Battery portable 4-channel scopes feature 70-Mpt memory, 1 GSa/sec sampling, 130,000 wfm/sec refresh rate
The Micsig STO1004 four-channel battery-powered portable oscilloscope offers 100 MHz bandwidth, 70 Mpts memory, 1 GSa/sec sampling (single channel), 130,000 wfm/sec refresh rate, and a 7.5-Ah lithium battery for extended field use. Improvements over previous Micsig models include an intelligent bidirectional Universal Probe Interface for accommodating and powering smart probes such as those with differential […]
The many measurements of power quality
There’s a confusing variety of ways to quantify power consumption. Make sure you understand what your favorite power metric means. To most engineers, the concept of power quality pertains to characteristics of the ac line feeding grid energy to equipment in a facility. But variations of the “power quality” term now can refer not just […]
Now out: The new Test & Measurement Handbook
Featuring 17 articles, the 2022 Test & Measurement Handbook looks at EMI, motor testing, 5G measurements, power quality, and other topics. Welcome to EE World’s 2022 Test & Measurement Handbook. We gathered a new collection of articles, some 17 in total. The articles in this year’s handbook look at Test & Measurement across hardware and […]
Will 60 Hz continue to be a frequency you can count on?
Leland Teschler • Executive Editor There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that supply […]
