Abstract
Interposers for tapping a signal. An interposer can include an interposer printed circuit board, an output connector that couples the interposer circuit board with a backplane connector of a chassis, an input connector for coupling the interposer circuit board with a disk drive, tapping circuitry for tapping a high-speed differential signal, and connectors coupled to the tapping circuitry for transmitting the tapped signal to an analyzer or an oscilloscope.
Claims25
An interposer, comprising:
- a printed circuit board;
- an output connector for coupling the printed circuit board with a backplane connector of a chassis;
- an input connector for coupling the printed circuit board with a disk drive;
- tapping circuitry for tapping a signal;
- and
- a first pair of connectors coupled to the tapping circuitry for transmitting the tapped signal.
