SPEKTRA develops exciters for vibration tests up to megahertz frequencies
For testing and characterizing sensors based on MEMS technologies, sensor manufacturers and their customers require increasingly high-frequency mechanical exciters that can generate both translational and rotational vibrations. Whereas 10 years ago, frequencies between 20 kHz and 50 kHz were still sufficient, tests are now already being carried out at frequencies of several hundred kHz – and the requirements for the near future are moving into the megahertz range.
