Set the Fmax in Advanced Transient


The Fmax defines the maximum frequency in the spectra. The Fmax setting is not continuous; it is a set of predefined values. The analyzer automatically selects the next higher value.
Note: If you change the Fmax, the sample time and sample rate also change.


  1. Activate a job.
  2. From the Transient main menu, press F1 Setup / Acquire Data > F2 Set Fmax.
  3. Enter a value between 10 and 20,000 Hz.
    The default is 200 Hz.
  4. Press Enter.
