sine frequency responce

[guido84]

Good morning to all,
I should do a "sine frequency responce" analysis of an object, I imagined I had to do a simple frequency response analysis, but between the input data I find myself a fact that I don't know how to use the "sweep rate". Can someone tell me the way to do this analysis with nastran?
thanks in advance

solved:
the analysis to do is a frequency response analysis (sol111) - the sweep rate is the speed at which the frequency is increased and is a parameter that is taken into account only when performing a test.
