If the correction frequency span is only a subset of the start/stop
frequency span set on the source, no corrections are applied to the
portion of the sweep that is outside the correction frequency span.
The following example illustrates how the data is distributed within
the user flatness correction array.
Assume that the swept CW generator is set to sweep from 2 to
18 GHz, but you only enter user flatness correction data from
14 to 18 GHz. Linear interpolation occurs between the correction
entries to provide the 401 points required for the 14 to 18 GHz
portion of the array. No corrections are applied to the 2 to
13.99 GHz portion of the array. Refer to Figure F-4.

Number of points interpolated between correction entries is
calculated as follows:
freq. span between correction entries
stop frequency - start frequency

1600 - 1 = Number of pts
When correction frequencies are arbitrarily spaced, the number of
interpolated points varies.
