Pure sinusoids are rarely encountered in the world of mechanical vibration. Due to that, the trend amplitude value is calculated by simply multiplying the peak amplitude by 0.707. But some analysts prefer to display the amplitudes as a 'peak' amplitude (usually because the vibration severity charts they are using are in peak amplitude values).

On the other hand, a switchover from the peak amplitude to the rms amplitude might hide a genuine rise in vibration amplitude. Finally, the amplitude and frequency units to be used in the spectrum also need to be specified. Which units should be used is really a matter of personal choice, or more often, geographic location.
