A horn analyzer is an test instrument dedicated to determine the resonance and anti-resonance frequencies of ultrasonic parts such as transducers, converters, horns/sonotrodes and acoustic stacks, which are used for ultrasonic welding, cutting, cleaning, medical and industrial applications. In addition, digital horn analyzers are able to determine the electrical impedance of piezoelectric materials, the Butterworth-Van Dyke (BVD) equivalent circuit and the mechanical quality fator (Qm).
