Application of Cross-spectrum FFT analysis

In this video, we shall consider implementation of Cross-spectrum FFT  analysis and the process of obtaining the AFR characteristic of a vibration transducer.

For the calibration we shall need a reference vibration system, which includes: shaker, controller, charge amplifier, reference vibration transducer, and the program Cross-spectrum FFT  analysis from the scope of ZETLAB software.
