Abstract
A batch test or burn-in board system has a driver/receiver board having a plurality of driver/receiver circuits that are used for burning in individual circuits on a second board in a desired environment. The driver/receiver board sends timed pulses to each of the circuits on the second board. Calibration values for insuring appropriate timing of the pulses from the driver/receiver circuits are stored in a memory that is mounted directly on the driver/receiver board. The calibration values are retrieved from memory under computer control for operating the driver/receiver board for the batch test or burn-in sequence.
