Experimental frequency response acquisition
For the frequency response data acquisition the WinFACT module FRED has been developed. It allows the experimental frequency response recording. For that purpose a Wobble generator is built up by using the WinFACT drivers which generates the different frequencies. Therefore a hardware is needed which at least has one analog output and, of course, one analog input.
range of the resonance frequency frequency points
were added afterwards (original size).
The main features of FRED are:
|integration of the WinFACT drivers|
|observance of the measuring range|
|quick and clear configuration|
|data processing by multithreading and threrefore a good real time performance|
|graphical presentation of the measurement as well as of all recorded time responses|
|saving of the measurements|
|adding and deleting of frequencies afterwards|
