Products within this family provide a convenient means of evaluating the performance or behavior of some focus device, in the context of a proven implementation that is generally well-documented and supported by evaluation software, as appropriate. Typically consisting of a printed circuit board on which the focus device has been populated along with necessary or helpful support components, additional components such as cabling or power supplies may also be included. Evaluation platforms for device classes that are particularly numerous or distinctive in their classification such as ADCs, DACs, and switch-mode power supplies may be grouped together as a separate product family.
