Description
The statistics are computed for all global levels of historic. The time
step of the global level historic can be adjusted between 50ms and
1000ms.
The dB/Lin. parameter allows choosing the amplitude scale format.
The choices are dB, dB(A), lin. rms, lin. peak or lin. rms2.
The Integration parameter allows applying simple or double
integration in the frequency domain for an acceleration
measurement. For the simple integration option, the power spectrum
is divided by jω. For the double integration option, the spectrum is
divided by –ω2.
