Abstract
A system for calibrating cables attached to a time measurement device is disclosed. The system includes a calibration device that generates a plurality of synchronized measurement signals that are communicated to a time measurement device by a set of cables. The calibration device can also generate at least one arming signal that is also communicated to the time measurement device. By determining the relative arrival time of a common reference event of each of the measurement signals, the time measurement device can determine any skew that exists between each of the cables that input the measurement signals. The skew can then be used to compensate for varying cable skew in future time measurements. In one embodiment, the system of the present invention can also be used to determine the arming latency of the time measurement device by delaying the measurement signals in relation to the arming signals and observing the delay time which causes complete synchronization of the measurement signals.
