With Thunderbolt 3 well established, Thunderbolt 4 coming onto the market, and Thunderbolt 5 in the early stages of being defined, it’s important that designers understand the similarities and differences between the various flavors of Thunderbolt and how they compare and contrast with USB. Intel designed thunderbolt technology in cooperation with Apple to support new […]
USB proliferation of capabilities and compatibilities
USB4 represents a significant change from past standards from the USB Implementers Forum (USB-IF). USB4 is based on the Thunderbolt 3 protocol. Support of Thunderbolt 3 interoperability is required on all ports for USB4 docks. It is required for downward-facing ports on hubs and is optional for USB4 hosts and peripheral devices. Like Thunderbolt, USB4 […]
What is 5G femto application platform interface (5G FAPI)?
The 5G femto application platform interface (5G FAPI, or simply FAPI) published by the Small Cell Forum (SCF) is a suite of specifications that enable small cells to be built up piece-by-piece using components from different suppliers. It can be viewed as a subset of the network functional application platform interface (nFAPI), also published by…

Unlicensed spectrum use: What’s the technology behind it?
Unlicensed LTE lets wireless carriers offload traffic to Wi-Fi frequencies, but it must coexist with Wi-Fi and not interfere. Here’s how it works.
AC/DC power supply testing and qualification – Virtual Roundtable, Part 2
Welcome to the second part of EEWorld’s two-part “virtual roundtable” discussion on ac/dc power supply testing and qualification. Today, we will be focused on power factor correction, leakage currents, and electromagnetic compliance assurance testing. Our panelists are: Yogesh Pai (YP), Tektronix Product and Marketing Manager for Power; Bill Griffith (BG), Power Products Marketing, with Keysight […]
AC/DC power supply testing and qualification – Virtual Roundtable, Part 1
Welcome to the first part of EEWorld’s two-part “virtual roundtable” discussion on ac/dc power supply testing and qualification. Today, we will be focused on various aspects of power supply efficiency, standby power, and static and dynamic output regulation testing. Our panelists are: Bill Griffith (BG), Power Products Marketing, Keysight Technologies: Johnnie Hancock (JH), Oscilloscope Product […]
mmWave signals: The effect on PCB traces, cables and connectors
The use of mmWave technology is growing across various applications, from 5G telephony to automotive systems and drones. At mmWave frequencies, Signal Integrity (SI) is a major concern. SI measures the signal’s ability to propagate without distortion or undue losses. It measures the quality, or distortion, of the signal passing through the printed circuit board…
International performance and safety standards for robots
Robots are being used to implement logistics tasks, industrial processes, personal care, medical procedures, and more. The growing variety of robot designs and the breadth of tasks that robots perform is driving a large number of specific performance and safety standards. This FAQ reviews emerging standards for industrial mobile robots, collaborative robots (also called ‘cobots’), […]
