Using ACT, how can I insert a PSD acceleration boundary condition?

The following script can be adapted:

    # Refer to analysis
    analysis= ExtAPI.DataModel.Project.Model.Analyses[0]
    # Insert PSD Acceleration
    BaseExcitation=analysis.AddPSDGAcceleration()
    # Select direction
    BaseExcitation.Direction=NormalOrientationType.XAxis
    # Define units
    FreqUnit='[Hz]'
    AmpUnit='[G G Hz^-1]'
    # Define frequencies
    f1=100
    f2=200
    f3=800
    # Define values for tabular load input
    BaseExcitation.LoadData.Inputs[0].DiscreteValues=[Quantity(str(f1) + FreqUnit),
    Quantity(str(f2) + FreqUnit),
    Quantity(str(f3) + FreqUnit)]
    # Define amplitude values
    Amp1=50
    Amp2=75
    Amp3=1
    # Define values for tabular load
    BaseExcitation.LoadData.Output.DiscreteValues=[Quantity(str(Amp1) + AmpUnit),
    Quantity(str(Amp2) + AmpUnit),
    Quantity(str(Amp3) + AmpUnit)]
    # Define Boundary Condition
    BaseExcitation.BoundaryCondition=PSDBoundaryConditionSelectionType.AllFixedSupports

Just one change in recent versions of ansys. The amplitude units is changed like below

AmpUnit='[gravity gravity Hz^-1]'
