Rohde & Schwarz, National Instruments, and Agilent Technologies have been busy over the past week with a variety of product and services introductions. Agilent kicked off the month by announcing that all new Agilent electronic test instruments sold after March 1 will be covered by a “bumper-to-bumper†3-year repair warranty. Ken Woonton, Americas services marketing manager for Agilent's Electronic Measurement Group, said the increase from one year to three years is the result of ongoing quality initiatives that, from 2002 to 2012, yielded unprecedented improvements in product reliability.
