Abstract
Systems and methods for analyzing data transferred through an SPI data bus are presented. In one exemplary preferred embodiment of the invention, an SPI data probe imitates an SPI device coupled to the SPI data bus and receives data from the SPI data bus so that the data may be analyzed. The SPI data probe transfers the data to an analysis unit without substantially altering impedance more than the SPI device would. The SPI data probe includes connectors configured for coupling the probe to the SPI data bus and for coupling the probe to an analysis unit. The SPI data probe also includes circuitry that may buffer, compensate and deskew the data as an SPI device would.
