In the past, if you needed a functional test system
you had to choose between a complete custom
solution — typically integrated by a local system
integrator — or a standard, off-the-shelf applicationcentered
system, typically delivered by an
instrument vendor. Building custom solutions often
involved major engineering effort and big expenditures,
and the systems were sometimes hard to
support and difficult to adapt for testing new
products. The standard, application-centered
systems often lacked flexibility and frequently
relied on proprietary standards or software.
