ABSTRACT:
A method and apparatus are used to calibrate uncelebrated test equipment using reference devices. For each device, the calibrated test equipment is used to test the device to obtain a reference specification value. One of the devices is then selected, and an electrical identification from the selected device is retrieved. The electrical identification is associated with one of the reference specification values. A channel of the uncelebrated test equipment is used to test the selected device to obtain a measured specification value. The reference specification value associated with the electrical identification is compared with the measured specification value. Based on this comparison, the channel is calibrated.
