EEVblog #1032 Part 5 – John Kenny Keysight Interview

Interview with John Kenny from Keysight
Final part 5 of 5

This one covers the design of the 34460 multimeter, dc-dc converter design, cost targets, isolation, 34410a sales, contract manufacturers, production lines, chip packages, the 34460a 1000V spec mistake, IEC61010 Rev3 new challenges in product design, safety hazards and standards, floating design, certified power bricks, standby power consumption, power factor correction, how PFC is now zero cost, real power switches, soft power buttons, cost targets for products, and the art of low cost product design,

John Kenny is presently the Technology and Efficiency Manager for the Electronic Instruments and Systems Group. After graduating from Lehigh University in 1978, he started in Hewlett Packard, working in our Modular Power System team, designing modular supplies, and later moved to our Lab and Industrial Power group, where he was involved in Analog, Digital and Firmware design for the next 20 years, involved in the rollout of our many programmable power products. In 2005, he moved into a new role as the Technology Manager for the System Products Group, which covered all of the GP products, including Power Products, DMMs, Function Generators, Counters and Data Acquisition products. He was directly involved in the development of the breadth of the GP products that you see in the Keysigt catalog today, with more on their way. Recently, as part of the reorganization in 2015 as part of the new Keysight, he became responsible for Technology and Efficiency management for most of our non-RF based products, as part of the EISG Center of Excellence, which includes products developed in Japan, Penang, Singapore, Loveland and Budd Lake.
