In the example embodiments, test signals sent from a transmitting system are received at a receiving system. The receiving system generates a determination signal indicating, in one embodiment, whether received signals have a desired relationship with respect to a clock signal at the receiving system. Timing of the clock signal or timing for transmitting signals may be adjusted based on the determination. In another embodiment, the receiving system generates a determination signal indicating whether the pulse width of a lone pulse signal equals a desired time interval. Equalization or pre-emphasis is controlled based on the determination signal.
