In general, Agilent's spectrum analyzers do not provide a way to read the x data points (frequency for a normal SA trace). To generate the frequency point array, you can do

frequency(n) = fstart + (n - 1) * ( fstop - fstart) / (numberofpoints - 1)

Where n goes from 1 to the number of points. This of course only works for linear frequency sweeps - logarithmic sweeps are a little more complicated.
