Order Tracking


Order Tracking normalizes data from equipment that has fluctuating speed. Data from equipment with variable speed can cause vibration frequencies to look “smeared” between adjacent frequency lines.

The tachometer input of the analyzer must have a reference pulse. The tachometer pulse is typically from the shaft turning speed, but it could be from a belt.

The resulting data is related to the reference pulse and is displayed in orders of turning speed. Frequencies that vary with turning speed do not look smeared in the data. Frequencies that do not vary with turning speed, like electrical line frequency, may look smeared. A marked frequency is not used for any special data acquisition.


  1. Create a job or open Analyze from a route measurement point.
  2. From the Analyze main menu, press F7 More Experts > F8 Order Tracking.
  3. Press Start or Enter to collect the data.
  4. Press Enter to view the data.
    One or more plots display after the data is collected.
  5. Press F9 Store Data to save the data to a route or a job, or press F8 Start to redo the measurement.
