Education & Academia

Producing first-rate engineers is a daunting responsibility. More and more, experimental skill and experience with technologically advanced instrumentation is demanded by industry. Today’s engineers need to be both analytically competent and experimentally capable. Leading universities have broadened their curricula and softened the edge between electrical and mechanical studies to serve this need. Economic constraints place a premium on cost-effective instruments that can perform a variety of tasks by changing software. Flexible licensing that allows hardware modules to be used separately around the campus or to be brought together to form a large channel count system is now essential.
