Abstract : A video tape recorder has been converted into a wide band instrumentation recorder. The 'A' scan from the ultrasonic tester is directly recorded, together with the operator's voice giving the location, transducer position and interpretation of test data. An oscilloscope is used for the playback. The circuitry necessary to couple the output of the ultrasonic tester to the tape recorder is described. (Author)
