VibSoft Data Acquisition Software

• Control of all vibrometer settings via RS-232 interface; all settings stored with the data files – ideal for test-stand installations and extensive test series (with most models)
• Integrated signal enhancement provides the best laser vibrometer performance
• Integrated function generator (option) including user-defined excitation waveforms–tight control and synchronization
• Provides live video images of the test object and laser beam position (optional)*for easy measurement point definition and documentation
• Acquires time and FFT response signatures for arbitrary drive voltages
• Averages the input signal in the time domain
• Differentiates and integrates in time and frequency domain
• Calculates FFT with up to 12,800 lines of resolution; optional zoom FFT and extended FFT resolution up to 819,200 lines available
• IEPE (ICP) support for third-party sensors (with most models)

* requires VIB-S-Video option, sensor head equipped with internal video camera and PC with video input

• Displays third octave, magnitude, real and imaginary, and Nyquist diagrams
• Provides complex spectral analysis with auto power, cross power, H1, H2, FRF, PSD, phase and coherence functions
• Applies digital high-low and band-passfilters
• Extensive peak analysis capability is enhanced by a band cursor providing statistical parameters and harmonic oscillator curve fitting. A harmonic cursor plots up to 12 cursor lines at the 2nd, 3rd, order of the base frequency
• Visual Basic Scripting (VBS) simplifies automatic test routines and enables interfacing with other software
• Exports data in ASCII and UFF; provides direct access to binary data for processing in MATLAB and LabView using the PolyFileAccess open data interface (Microsoft COM standard)

VibSoft-VDD is a software package for PC-based vibrometer systems. In the VDD system, a quadrature demodulator generates the sine and cosine components of the sensor head signal. These are digitized by a high-sampling-rate ADC board inside the Data Management System to measure the dynamic displacement of the test object. The VDD PC-based digital vibrometer is an excellent tool to characterize very small dynamic displacements with a bandwidth up to 2 MHz, flat response and a solution of 2 pm.
