The HFPA series power amplifiers can be applied to various ultrasonic testing scenarios. For example, in ultrasonic guided wave testing, they can be used to excite ultrasonic probes to generate guided waves in plates or pipes. In resonant ultrasound spectrum testing, the swept-frequency signal can be amplified by the power amplifier and then serve as the excitation signal for the probe.
