Eval Range
Opens a dialog to define the range for the statistical and phase evaluation and for the x-dB compression
point measurement. The evaluation range is a continuous interval of the sweep variable.
It is possible to select, define and display up to ten different evaluation ranges for each setup. Full Span
means that the search range is equal to the sweep range. The statistical and phase evaluation and the
compression point measurement take into account all measurement points with stimulus values x
i
between the Start and Stop value of the evaluation range:
Start x
i
Stop
The evaluation ranges are identical to the marker search ranges. For more information see
Search Range Dialog.

Smoothing On
Activates the smoothing function for the active trace, which may be a data or a memory trace. With
active smoothing function, each measurement point is replaced by the arithmetic mean value of all
measurement points located in a symmetric interval centered on the stimulus value. The width of the
smoothing interval is referred to as the Smoothing Aperture and can be adjusted according to the
properties of the trace.
The sweep average is an alternative method of compensating for random effects on
the trace by averaging consecutive traces. Compared to smoothing, the sweep average
requires a longer measurement time but does not have the drawback of averaging out
quick variations of the measured values.
