Abstract

An ultrasonic test set is calibrated in terms of its frequency characterization by establishing a response trace on a monitor screen of the test set when the probe of the test set is applied to a standard test article, a digitizing camera is arranged for scanning the trace on the test set monitor, and a digital computer receives the digital output signal on the digitizing camera and processes the signal by sampling the signal trace at discrete points with respect to time; the digital computer provides an output on output means such as a monitor screen and/or printer which provides information on the frequency characterization of the ultrasonic test device and includes a frequency spectrum. The apparatus can be implemented by a combination of commercially available and known separate elements providing a cheap and effective apparatus and method for calibration purposes.
