Keysight Technologies, or Keysight, is an US company that produces test and measurement equipment and software. In 2014, Keysight was spun off of Agilent Technologies, bringing with it the product lines focused on electronics and radio, leaving Agilent with the chemical and bio-analytical products.The name is a portmanteau of key and insight, and was chosen to convey that the company "unlocks" "critical or key insights."
