Patent ID: 8261119

Claim:
A test apparatus for testing a device under test, comprising: a plurality of test modules that test the device under test; a synchronization module that is connected to each of the plurality of test modules, the synchronization module synchronizing together the plurality of test modules and including: an aggregating section that aggregates synchronization signals received from one or more of the plurality of test modules to generate an aggregated synchronization signal; and a distributing section that distributes a control signal indicating an operation corresponding to the aggregated synchronization signal to a to-be-controlled test module of the plurality of test modules, wherein the synchronization module synchronizes an analog module to a digital module by transmitting to the analog module a control signal corresponding to an aggregated synchronization signal generated by aggregating a synchronization signal received from the digital module, and the digital module is one of the plurality of test modules that exchanges a digital signal with the device under test, and the analog module is one of the plurality of test modules that performs an analog test on the device under test.
