Hi,

Thanks to harmonic analysis I calculated FRF, I used 9800 mm/s^2 as acceleration data. Vibration generator is g^2/Hz in nCode DesignLife, and my PSD datas changes from 0 Hz to 2000 Hz as g^2/Hz. Since I used mm/s^2 in harmonic analysis, must I convert g^2/Hz to mm/s^2/Hz in nCode? 

Are they same unit both in harmonic analysis and in nCode DesignLife?
