Vib'SYS
Digital Signal Processing and Analysis Software 



Introduction
This set of software of vibration signal acquisition, processing and
analysis was developed on the basis of many years of practical experience
in the vibration testing projects. The software has been applied to
a variety of vibration testing. It has provided a complete set of vibration
signal analysis tools to solve practical vibration engineering problems.
Researchers as well as students can process and analyze various vibration
signals without the need of developing any programs. It is convenient
to use for both experienced vibration analyzers and nonprofessionals.
Our company provides complete software application training, technical
support and detailed operation instructions.
