Abstract
A calibration device is provided for use with automatic test equipment (ATE). The calibration device includes circuitry having a fanout circuit. The compare-side fanout circuit has an input connected to a first channel of the ATE and outputs connected to N (N>1) channels of the ATE, where the N channels do not include the first channel. The ATE propagates an edge on the first channel, and the fanout circuit transmits the edge to the N channels. Optionally, a calibration device for use with automatic test equipment includes a drive-side circuit. The drive-side circuit includes circuitry having multiple inputs connected to N (N>1) channels of the ATE and an output connected to a second channel of the ATE that is not one of the N channels. The ATE propagates an edge on each of the N-channels and the circuitry propagates each edge to the second channel of the ATE.
