Alternatively, you can use a batch process model to control a set of test sockets that test multiple UUTs as a group. For example, you might have a set of circuit boards attached to a common carrier. The batch model ensures you can start and finish testing all boards at the same time.
The batch model also provides batch synchronization features. For instance, you can specify that the step runs only once per batch if a particular step applies to the batch as a whole. With a batch process model, you can also specify that certain steps or groups of steps cannot run on more than one UUT at a time or that certain steps must run on all UUTs simultaneously.
