This paper reports on the evaluation of several modal-testing procedures as applied on a modern data-acquisition and -analysis system. These methods include two forms of specimen excitation (sine and multifrequency) and several methods of modal characterization (analytical curvefitting, multishaker modal tuning, and hybrid techniques). The methods are compared, using examples, and a modal testing procedure is suggested.
