Determining gradient field-induced vibration of a device typically involves multiple measurements at discrete frequencies. This study compares data from a frequency chirp to discrete frequencies in an effort to decrease testing time and obtain a larger range of information. Results confirm scaled displacement obtained through discrete frequency measurements and a frequency chirp matched for all measured frequencies.
