  Key Concepts: 
  Order Spectrum is a feature of the Vibration Analysis component of SAP PM-PDM-VA. It is used to analyze the frequency spectrum of a vibration signal and identify the frequency components of the signal. The order spectrum is used to identify the source of the vibration, such as a bearing defect or an imbalance in a rotating machine. 
  
  How to use it: 
  The order spectrum can be used to analyze vibration signals from rotating machines, such as pumps, motors, and fans. The order spectrum is generated by taking a Fourier transform of the vibration signal. This Fourier transform is then used to generate a graph that shows the frequency components of the signal. The order spectrum can then be used to identify the source of the vibration. 
  
  Tips & Tricks: 
  When using the order spectrum, it is important to ensure that the vibration signal is free from noise and other interference. This will ensure that the order spectrum accurately reflects the frequency components of the signal. Additionally, it is important to ensure that the sampling rate of the vibration signal is high enough to capture all of the frequency components. 
  
  Related Information: 
  The order spectrum can be used in conjunction with other analysis techniques, such as modal analysis and time-frequency analysis, to further analyze and identify sources of vibration in rotating machines. Additionally, it
