With the SKF analyzer and software the vibration data, the time waveform and spectrum units will be in units of the transducer, in your case velocity. However, in the software you can convert the spectral data into displacement and acceleration. Just right click in the spectrum plot and select the unit you want. Right click and select "Reset settings" to bring back to the original unit. The time waveform data is not convertible. In your case it will be in velocity units.
