Acceleration is a quantity derived from velocity.
Easiest is to loop over velocity data and calculate: a = i*ω*vel and ω = 2*pi*freq
a) RMS_a: a = ω * vel
b) PSD_a: a2/bandwidth
c) PSD_g: (a/g)2/bandwidth
where "bandwidth" can be retrieved by using:
bandwidth = pi_fFreqDomainGetBandwidth(fdom, BandIndex)
