I have a SRS as imput for my system ( due to a pyro-shock) and I have to analyze the response .  If I try with a RSA i get too conservative data also with SRSS method ( Is that right ?). I would like to have a graph  that shows the acceleration function of frequency to see the maximum , for armonic analysis it's easy to plot it while for RSA seems to be not possible : Is that rigth ?

If you have any ideas or anything else that might help me please share your thoughts . Thanks you
