KRUE101: ASD stands for “Acceleration Spectral Density” and PSD stands for “Power Spectral Density” If you are using vibration data ASD and PSD are the same. PSD was used in the acoustics world many years ago and has been carried over into vibrations world. The units of ASD and PSD are G^2rms/Hz.
What is difference between ASD and PSD?
(Note that regardless of popular opinion, G2/Hz is actually an acceleration spectral density (ASD), not a power spectral density (PSD).

| 600.00 Hz | 0.0500 G2/Hz |
| -4.02 dB/Oct | |
What is PSD level?
In vibration analysis, the PSD stands for the Power Spectral Density of a signal. … The PSD represents the distribution of a signal over a spectrum of frequencies just like a rainbow represents the distribution of light over a spectrum of wavelengths (or colors).
