Abstract :
This paper presents a philosophy of semiautomatic checkout, along with a description of the Mark 6 (Titan II) Re-entry Vehicle Test Set. This test set is used for testing both R&D and Operational Re-entry Vehicles. Included is a discussion of checkout philosophy as it affects the test set, circuit concepts, operation, trouble-shooting, packaging and maintenance concepts. This checkout philosophy was used as a basis for testing medium complexity vehicles where the checkout time is not extremely critical.
