With the vibration test stand, you can carry out component tests according to your specifications in a time- and cost-efficient manner. The high frequency resolution enables frequency determination with an accuracy of <1Hz. The determination of resonances and modal parameters is automated and does not require expert knowledge on the part of the operating personnel. Thanks to project-based organization in a database, you can keep track of all measurements at all times.
