Data acquisition and analysis for laser vibrometry

VibSoft is a comprehensive and easy-to-use software package for digital vibration data acquisition and analysis. VibSoft closes the gap between raw signal acquisition and profound analysis of vibration measurement data, offering optimum performance with laser
Doppler vibrometers. 

VibSoft is available for both analog and fully digital data transfer. Choose between three versions VibSoft-VL, VibSoft-20 and VibSoft-PRO: Whether your testing applications require analog or fully digital data acquisition up to 25 MHz or multi-channel DAQ that allows connecting additional inputs like complementary sensor signals. When mobility is key, benefit from a lean, portable and WLAN connected laptop solution.


  • Powerful DAQ and analysis from DC up to 25 MHz
  • Fully digital or multi-channel analog
  • Available as portable laptop solution
  • Control all vibrometer settings remotely
  • Real-time video imaging of test objects
  • Comprehensive toolbox for analysis in time and frequency
  • Sample excitation via internal signal generator
  • Individual post-processing with Polytec signal processor
  • Integrated scripting interface

Fully digital data acquisition for vibration analysis

VibSoft provides both data acquisition and profound analysis of vibration measurement results. Using a VibSoft junction box, an analog vibrometer signal can be acquired and analyzed together with other analog input signals (sensors or reference signals). Polytec measuring instruments equipped with a corresponding VibroLink interface can communicate directly with VibSoft or VibSoft-VL via Ethernet or WLAN. This enables the transfer of measurement data and remote control of the measurement parameters fully digitally.

VibSoft offers digital high, low and bandpass filters. The software is open to common standards: for example, recording the time and FFT data for arbitrary voltage signals, supporting IEPE (ICP®) for sensors from third-party suppliers, providing Visual Basic for automatic test routines or exporting in the ASCII and universal file format. 

Further options like real-time video imaging, the powerful signal processor (a Polytec math library for post-processing) and a scripting engine for individual post-processing and control make VibSoft an extremely powerful tool.
