High speed data computations and routing rely on incredibly complex circuit board designs with data transfer rates fast approaching picosecond timing precision (that is one trillionth or one millionth of one millionth of a second). To ensure new products fulfill design expectations, circuit boards must be measured to ascertain data signal quality and confirm circuit simulations. The following article explores some of the most common measurement methodologies used in validating high speed circuit board designs.
