I'm not sure I'd describe Keysight as a success story of cutting edge R&D, I can't speak for the current Agilent as I'm not a chemist. They and other namesake test equipment brands seem to only focus on the ultra high end and the lower to even midrange models are frequently white labeled products from overseas competitors with a more polished UI. And they're not even always pushing their top end stuff further, their top end multimeter is virtually unchanged since 1990.
