SPEKTRA develops and produces a wide variety of vibration and shock exciters, which could be used in calibration systems as well as in measurement and test systems of small objects (e.g. sensors, electronic components, …) or to apply defined dynamic forces to larger mechanical structures for modal analysis. They also have power amplifiers to drive any vibration or modal exciters.
As a whole turnkey system, we provide vibration and shock test system from PROSIG to measure, record and analyze the vibration and shock pulses.
The overview of the vibration test system is shown below.
