Abstract

An apparatus for testing a device. The apparatus comprises a test control module and a test analysis module. The test control module is operable to generate and transmit first prober and handler (PH) requests to a supervisor module. The supervisor module is operable to transmit first PH commands to a prober and handler for execution thereof. The test analysis module is operable to generate and transmit second PH requests to the supervisor module. The supervisor module is further operable to transmit second PH commands to the prober and handler for execution thereof. The execution of the second PH commands are performed transparently to the test control module.
