An apparatus for testing electronic devices that output high-speed serial data bit streams employs a programmable device to adjust the timing of the strobe so that the data bit stream being analyzed is strobed at or near the center of the bit. The distributing unit includes an input port, multiple output ports and multiple control pins. The controller performs an initialization phase in response to receiving power and enables the keep awake signal after completing the initialization phase. The invention further comprises an in situ pipe repair device including an inflation component of first end piece and a second end piece, each having a fixed dimension and wherein at least one end piece has a fluid access port and at least one electrical conductor access.
