Acquisition technology has seen major changes in the last few years,
particularly with the adoption of new bus technologies. Traditional
frame grabber technology has been joined by a range of generic
interfaces such as FireWire and USB (2.0 and 3.0) along with Gigabit
When designing a system, users often focus solely on the technology
required to make the acquisition work. A lot of time is spent diagnosing
why systems have intermittent failures and the answer is often to be
found in a lack of thought in the design of the interfacing hardware.
