ICC InternationalGene Vogel
EASA Pump & Vibration Specialist

Spectrum analysis is the primary tool for analyzing vibration problems. Yet, a lot of useful information can be acquired by tracking the vibration characteristics as power is disconnected from the machine. Most spectrum analyzers have a function for capturing the coast-down data. Knowing how to setup and use that instrument function is important for many vibration analysis and balancing situations. 

Topics in the presentation include: 

  • Applications for coast-down analysis 
  • Bode and Nyquist plots 
  • Basic instrument setups for many analyzers 
  • Interpreting results 

Target Audience: Vibration and balancing technicians, supervisors and engineers will benefit from this practical review of basic vibration analysis tool.
