Abstract : The application of digital-computing techniques to automatic checkout systems for electronic equipment was investigated. The incorporation of a general-purpose digital computer in an automatic test system can result in reducing technical manpower requirements and elimina ing he ee for pecialized quip ent for each task, as well as si plifyi g an speeding up both the preparation and execution of chassis test procedures. Methods for testing chassis for the purposes of fault isolation and circuit adjustment are discussed. BRIDG -ME UR T CHN U THO OF EVALUATING ACTIVE ELEMENTS, SUCH AS VACUUM-TUBE PARAMETERS, BY MEANS OF TESTS USING TRANSIENT-TYPE STIMULI ARE DESCRIBED. A study of ten schematic diagrams, which are representative of existing electronic equipment of the vacuum-tube type, indicates that about 90% of the passive eleme ts in a c i can be individually evaluated using nonoperational steadystate tests if the number of accessible connections is equal to one-half the total number of components. The application of computers to automatic checkout systems will permi ub a ial improvements in the capability of such systems on the basis of existing technology. (Author)
