VibSoft is a comprehensive software and hardware package for acquiring and pro-
cessing data from Polytec’s line of single-point laser vibrometers. It manages the data
acquisition, signal decoding, function generator, data display and remote control
of vibrometer controller settings. Measurements can be presented in both time and
frequency domains with applying digital filters, signal averaging as well as real-time
integration and differentiation.

Powerful Options
The performance of VibSoft can be greatly
enhanced by adding appropriate hardware and
software options. Various external or internal
function generators support a wide range of
arbitrary waveforms for sample excitation.
The Polytec Signal Processor is a powerful user
interface to the math library included in VibSoft.
Designed as an easy-to-use spreadsheet, meas-
urement data from different sources can be post
processed by simple drag and drop operations.
Data can easily be shown in one plot, subtracted
from a trace in another plot, and integrated in
a third plot.
