A new version of the USB spec puts additional demands on testing regimes that wring out power-handling options. David Maliniak | Teledyne LeCroy Since its official debut in 1996, the Universal Serial Bus (USB) protocol has seen numerous revisions spanning three generations of the standard, with USB 4.0 waiting in the wings for later in […]
Test instruments that aid PCB repair tasks
Basic tools such as DMMs and oscilloscopes may be the only test gear needed for small printed circuit board repairs, but it pays to know when automated systems would be a better choice. Alan Lowne | Saelig Co. Inc. PCBs are more complicated to repair today than even a few years ago. Manufacturing mistakes and […]
What you should know about Wi-Fi 6 and the 6-GHz band
While there are still interference issues to be resolved, new specifications for Wi-Fi in the 6-GHz band will bring instantly better wireless performance. Eve Danel | LitePoint Wi-Fi technology turns 20 this year, and it has proven to be successful beyond the wildest expectations. The recent announcement by the FCC to consider allowing 1,200 MHz […]
How standards and conformance tests shape the future of 5G New Radio
Specs for 5G NR release-15 have been finalized and plans call for product introductions this year. Sheri DeTomasi | Keysight Technologies, Inc. The development of 5G standards and their commercial rollout appears to be on a fast track. Mobile operators and network equipment makers are conducting field trials and the first smartphones are expected out […]
Test instruments tackle 5G
The high frequencies involved in 5G will force a re-think of how to go about characterizing circuits and systems. Adnan Khan | Anritsu Co. Engineers responsible for designing and manufacturing 5G chipsets, devices, and systems have more than enough challenges. From a technical standpoint, they must deliver high bandwidth, low latency, and other performance benchmarks. […]
Will 5G be lethal?
Leland Teschler, Executive Editor Peruse a certain kind of website these days and you’ll find warnings about the lethality of RF transmissions in the frequency ranges slated for 5G networks. One site quotes Devra Davis, director of the Board on Environmental Studies and Toxicology of the U.S. National Research Council, who warns that our sweat […]
Web-based jitter measurement utility gives product designers critical timing test results in minutes
The new Jitter Measurement Utility is a web-based, fully automated tool that enables designers to quickly and easily evaluate the jitter and phase noise performance of their custom clock configurations without using their own test equipment. “The need for higher timing performance is being driven by the introduction of new technologies such as 5G, mmWave, […]
PCB testing apparatus equipped with repositionable fine-point spring-loaded probes
The Sensepeek PCBite System is a professional-yet-affordable PCB testing apparatus with a system of repositionable fine-point spring-loaded probes, a large (8.3×11.7-in) metal baseplate, and four magnetic-base PCB holders for clamping circuit boards in a stable, fixed position. The probes are attached to a flexible, stable gooseneck arm that has a powerful magnetic base, and the […]
Test gear rapidly detects, locates, report optical fiber breaks up to 100 m away
A new testing solution detects problems within optical fibers. AddOn’s EON-NSV-OTDR devices rapidly locate and report any faults in an optical fiber link of a communication network – saving service providers time and money by allowing them to quickly address the root cause of any issues. The detection of problems within optical fibers is critical […]
New device accurately measures gap, vibration and positioning
A third-generation digital capacitance displacement gauge features low noise and industry-leading resolution. The Accumeasure D Series (“Gen 3”) is designed with OEM customers in mind. With both analog and digital outputs, the Gen 3 can be seamlessly integrated into products to measure, monitor, and provide instant closed loop feedback for critical process parameters including gap, […]
