Calibration exciters, also known as 'shakers', generate defined mechanical, acoustic and dynamic signals that can be used to test and calibrate sensors, measurement instruments, and complete measurement chains with precision. They are used in calibration laboratories, sensor development and quality assurance, as well as in research and development.
SPEKTRA calibration exciters deliver reproducible reference signals across wide frequency, amplitude and acceleration ranges, making them ideal for measuring acceleration, shock, pressure, acoustics and rotation rate. Thanks to their modular design, they can be easily integrated into existing test benches to enable compliant, traceable calibrations.
Typical applications include calibrating sensors and systems, performing NVH analysis, and conducting environmental and stress testing and reference measurements.

What is a calibration exciter?
A calibration exciter generates defined physical stimuli for testing and calibrating sensors. A known reference value is compared with the sensor signal to determine deviations and derive calibration values.
Depending on the application, calibration exciters generate, for example:
- mechanical vibrations for calibrating accelerometers.
- defined shock pulses for shock sensors.
- acoustic or pressure-based signals for microphones or pressure sensors.
- controlled rotations for yaw rate sensors.
In calibration laboratories, such tests are often performed in accordance with the DIN EN ISO/IEC 17025 standards, with traceability to national standards.
