Syntax spectNode = GetSourceSpectrum( srcNode )
Parameters spectNode (Long) Node number of the spectrum currently applied to the source.
srcNode As Long Node number of the source being modified.
Remarks The following example finds the node for a source and then queries the source for the applied spectrum.
