Abstract: A backplane testing system includes a test backplane coupled to a test device chassis and including a first connector system, a second connector system, and channels that connect the first connector system and the second connector system. A first test device in a first test device slot on the test device chassis engages the first connector system and provides a loop back circuit for the first connector system. A second test device in a second test device slot on the test device chassis engages the second connector system. The second test device sends a test signal through a channel on the test backplane such that the test signal is provided to the loop back circuit on the first test device and received back through the channel. The second test device analyzes the test signal that is received to determine a testing compliance of the channel on the test backplane.

Abstract: A differential trace pair system includes a board having a first board structure member and a second board structure member. A differential trace pair in the board includes a first differential trace pair portion of a first width outside the board structure, and a second differential trace pair portion of a second width extending through the board structure. A first outer edge and a second outer edge of the second differential trace pair portion define the second width that is less than the first width. A first board structure member channel is defined by the first outer edge adjacent the first board structure member, a second board structure member channel is defined by the second outer edge adjacent the second board structure member and the first and second board structure member channels provide a third width of the second differential trace pair portion that is less than the second width.
