Abstract
An apparatus for measuring characteristics of a at least one Power Over Ethernet (PoE) Power Sourcing Equipment (PSE) device (also referred to as a PSE test blade) is presented. The apparatus includes a port controller and a current loading circuit in communication with the port controller. The apparatus further includes a resistance loading circuit in communication with the port controller, a capacitance loading circuit in communication with the port controller, and a load current and voltage measuring circuit in communication with the port controller. The apparatus further includes a first network providing the power signals to at least one of the current loading circuit, the resistance loading circuit, the capacitance loading circuit, and the load current and voltage measuring circuit. The port controller utilizes a set of test primitives which are accessed in real time via a user interface to execute test sequences for characterizing PSE devices.
