Welcome to this Virtual Interview on power distribution network (PDN) integrity in embedded systems. We are here today with Heidi Barnes (HB), Senior Application Engineer for PathWave EDA for High-Speed Digital with Keysight Technologies. The following is from an interview with Heidi by EEWorld’s Jeff Shepard, where they discuss printed circuit boards, ground planes, and […]
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’), […]
Sentient robots and artificial intelligence
Sensors for touch, vision are on the leading-edge of robotics developments. Sensors enable robots to gather information about the environment, determine how the environment may be changing, and provide the data to determine the appropriate response to any changes. Sensor information can be used to improve performance of the task at hand, or it can […]
Robot software environments and motion control architectures
Robots can be classified by their kinesiology, their mechanical performance specifications, and various types of software they employ. This FAQ will consider robot software environments and motion control architectures. The next FAQ will delve into “Sentient robots and artificial intelligence.” The series will conclude with a review of the major “International performance and safety standards […]
Robot axes, drive safety, and power architectures
Depending on the intended tasks and the associated range of motion, robots can have varying axes and various axis configurations called robot kinesiology. This FAQ will consider robot axes, kinesiology, drive safety functions, and power architectures. Subsequent FAQs will focus on “Robot software environments and motion control architectures,” “Sentient robots and artificial intelligence,” and “International […]
Validating power integrity in embedded systems
There are two primary considerations when validating power integrity in embedded systems; the operation of the various power converters and the power distribution system’s integrity. The relative importance of those two considerations depends, in part, on the power system architecture used. In systems with a centralized multiple-output ac/dc power supply, the power supply qualification is […]
