Spektra Structural Testing

Structural Testing

APS has been a well-known supplier of modal exciters for 45 years. In 2008 SPEKTRA and APS joined forces and together have built a new generation of even stronger exciters together – based on decades of know-how from both sides. Do you need to ensure the structural stability and endurance of your equipment under stress? Would you like to verify your product’s properties? Do you need modal exciters for tests in your laboratory or in the field? SPEKTRA will find a solution for your individual measurement task.

Vibration Control Systems

The VCS by SPEKTRA is a family of vibration control systems for environmental simulation tests using vibration test systems.

Modal Exciters

SPEKTRA develops and produces a wide varity of vibration and shock exciters, which can be used to apply defined dynamic forces to larger mechanical structures for modal analysis.

Power Amplifier

The amplifiers have features which make them uniquely suited for studying the dynamic characteristics of structures. They may be operated in either voltage or current amplifier mode.


For sensor calibration and other vibrational investigation, versatile accessories for mechanical and electrical adaptation are required. SPEKTRA offers a wide variety of cables and adapters.

Modes of Operation

Various optional accessories allow different modes of operation and facilitate handling of the equipment.

System concept

We provide well-balanced sets of exciter, amplifier, controller and sensor to get optimal performance and high precision in a wide range of applications.


Our software is a perfect match to the National Instruments hardware. It is a LabVIEW-based software solution. So it can easily be integrated into your environment.
