5. Define the frequency ranges ("Range Start" and "Range Stop") over which
you would like to integrate.
The application calculates the measurement results as defined. Result in the
integrated measurements result table are adjusted accordingly (see
on page 58 for a description on how to view that table).

applied to trace 2)
Note that the integration ranges are displayed graphically in the noise dia-
gram.

The Cross-Correlation Gain Indicator
How to control the cross-correlation gain indicator (gray area)
The gray trace, or cross-correlation gain indicator, indicates the ideal position of
the measurement trace for the current number of cross-correlation operations.
Thus, the position of this area depends on the number of cross-correlations that
are currently applied in each half decade.
This in turn indicates that measurement traces that are close to the gray area
(even if only in places) can be improved by increasing the cross-correlation oper-
ations. On the other hand, when the measurement trace lies above the gray area
throughout (about 10
dB), it is not possible to improve the results any more.

log box.
