Patent ID: 7177777

Claim:
An apparatus having a plurality of test modules that operate to test an electronic device, comprising: a first test module for generating test signals for the electronic device, the first test module having a device programmed to generate a first partial trigger signal and to delay the first partial trigger signal by a first delay amount; and a second test module for generating test signals for the electronic device, the second test module having a device programmed to generate a second partial trigger signal and to delay the second partial trigger signal by a second delay amount, wherein the first delay amount comprises a pipeline delay component and the second delay amount comprises a pipeline delay component, and wherein the pipeline delay component of the first delay amount differs from the pipeline delay component of the second delay amount by an amount that is equal to a difference in actual pipeline delays of the programmed devices of the first and second test modules, and wherein a confirmed trigger signal is generated from at least the first and second partial trigger signals.
