1.1 This guide describes procedures for electronically measuring the following performance-related characteristics of some sections of ultrasonic instruments:
1.1.1 Power Supply Section: line regulation, battery discharge time, and battery charge time.
1.1.2 Pulser Section: pulse shape, pulse amplitude, pulse rise time, pulse length, and pulse frequency spectrum.
1.1.3 Receiver Section: vertical linearity, frequency response, noise and sensitivity, and dB controls.
1.1.4 Time Base Section: horizontal linearity, and clock (pulse repetition rate).
1.1.5 Gate/Alarm Section: delay and width, resolution, alarm level, gain uniformity, analog output, and back echo gate.
1.2 This guide complements Practice E317, and is not intended for evaluating the performance characteristics of ultrasonic examination instruments on the inspection/production line.
