Method of adjusting ultrasonic test systems

Abstract From the Canadian patent

An ultrasonic test system for inspection of structural material includes a test electronics for controlling a plurality of ultrasonic transmitter and receiver channels. This test electronics is operated by sequencing the system through the several channels but the evaluating circuit, is common to the receive channels. The duration of the test timing of, launching, timing of beginning receiving response signals time and duration, of looking windows for identifying and timing particular responses and, comparison data, all are operating and acquisition parameters for operating the electronics. These parameters are furnished from external sources and are programmable and exchangeable, e.g. from …
