SOFTWARE SPECIFICATIONS

The PC/ANALYSIS approach to vibration testing provides an intuitive, easy to use interface to efficiently manage the complete test process and increase productivity. Set-up times are reduced and inputs are monitored to reduce errors and to flag values that exceed system limits. At the other end of the test process, data analysis and hard copy presentation functions emulate and automate the work flow of the engineer. More than just generic data acquisition capabilities are provided thereby increasing productivity and returns on your investment.
