1. A manufacturing test and programming method implemented on a tester station, the method comprising: receiving responsive to a printed circuit board (PCB) tester activation of a PCB tester interface a start signal indicating that a programmable device is to be programmed, wherein the programmable device is attached to a device under test, and wherein the device under test is detachably mounted on the tester station: loading, utilizing an in-system programmer electrically attached to the PCB tester, characterization data onto the programmable device, wherein the characterization data is configured to, when executed on the device under test, cause the device under test to perform one or more functions; determining whether loading the characterization data onto the programmable device caused the programmable device to be successfully programmed; in the event that the programmable device is successfully programmed, asserting a PASS line through one or more optical isolators to indicate to an external device that the programmable device was successfully programmed: and in the event that the programmable device is not successfully programmed, asserting a FAIL line through one or more optical isolators to indicate to an external device that the programmable device was not successfully programmed.
