Description: Returns the pdf value at the specified time.
Syntax: PDF_S(Data_Src, Time, [SL_1])
Data_Src is the source data sheet from which the pdf value is calculated.
Time is the time at which the pdf value is calculated.
SL_1 is the stress level, for each stress type, at which the pdf value is calculated. The number of stress level inputs is determined by the number of stress types in the specified data sheet.
Remarks:
The Data_Src can be one of the following values:
If using a default data source, it must be either 1, 2, 3 or 4, as selected from the Data Source Index drop-down list.
It can take a data sheet name (e.g., "Folio1!Data 1").
It can take a variable name defined in via the Defined Names window (e.g., datasource).
The Time value must be greater than 0.
SL_1 is an optional value. The default value is the use stress specified in the Use Stress Level window, but you can change the value to any desired number. If the data sheet uses the Cumulative Damage model, you can also use a stress profile for this value.
Example:
PDF_S("Folio1!Data 1",1000,356) = 1.4512E-7
Note that this value will vary depending on the source data set.
