High Frequency Analysis


Attach the sensor to the analyzer and the machine.


High Frequency Analysis acquires data beyond the maximum frequency of the route point or marked spectra. A spectrum displays the data using an Fmax of 5,000 Hz or it multiplies the Fmax specified in the route by 2.

Use High Frequency Analysis when many peaks are on the right side of the spectrum or when a high frequency band, such as HFD, is in alarm.


  1. Create a job or open Analyze from a route measurement point.
  2. From the Analyze main menu, press F4 High Frequency Analysis.
    If you disabled the help text, data collection begins.
  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.
