METHODS AND DEVICES FOR TESTING A DEVICE UNDER TEST USING TEST SITE SPECIFIC CONTROL SIGNALING
Embodiments of the present invention provide an automated test equipment (a “tester”) for testing a device under test, including a bidirectional dedicated real-time handler interface. Some embodiments include an interface having a trigger function, a fixed endpoint interface, an interface arranged on a test head, and/or a number of lines/communication channels adapted to a specific communication task, without separate signal lines, for example. The bidirectional dedicated real-time handler interface can be used to transmit a synchronization signal or other information to the handler in real-time, and the transmitted signal can be test site specific. The real-time signaling advantageously improves testing accuracy and efficiency.
