Probing the device under test is
both one of the potentially most
difficult and certainly one of
the most important tasks in
debugging a digital design. That
is why Agilent Technologies
provides a wider variety of
probing solutions than anyone
else in the industry—each with a
different set of advantages
particular to a given situation. We
like to think of it as helping you
get your signals off to a great
start.
