Abstract:
1. An apparatus for testing electronic devices, comprising: a test module having a transceiver, coupled to a pair of bidirectional conductive lines comprising a first line and a second line, for supplying test signals to an electronic device to be tested through said pair of bidirectional conductive lines and for receiving response signals from said electronic device over said pair of bidirectional conductive lines; a power source, coupled to said pair of bidirectional conductive lines, for supplying power to a power grid of said electronic device through said pair of bidirectional conductive lines, wherein test signals and power source signals are supplied separately; a circuit, coupled to said pair of bidirectional conductive lines, wherein said circuit is operable to couple said power source to said power grid of said electronic device, and wherein said circuit is operable to couple said test module to said electronic device, and wherein said circuit is operable to provide test signals to a portion of said electronic device separate from said power grid, and wherein said circuit is operable to provide power source signals to said power grid.
