Syntax:
dBize,'filename'
the filename argument is optional. If present, it is a string enclosed in single quotes giving the name of the file in which resides the extracted AOS spectrum (see PlotSpectrum). The file extension should not be given, and is taken to be .AOS.

Example:
dBize,OverPlot=[0,2,4,6]

Options:
/fullrange,
set this switch to plot to the full range in power and frequency

which=n,
The variable n is an integer value telling LinPlot which spectrum to plot from the currently loaded AOS spectra. This option overrides the 'filename' argument.

refwhich=n,
plot referenced to the AOS spectrum specified by the integer value n. The result is the ratio of the two spectra.

OverPlot=N,
Plot a number of spectra together. The variable N is an array of integers giving the indexes of the spectra to plot together. See example above.
