parameter. The formula for PD above is for transmission parameters. See the section
on "Length and delay measurement" in
Chapter 8.6.1.3, "Auto Length"
Tip:
The phase evaluation can cause misleading results if the evaluation range con-
tains a 360 deg phase jump. The trace format "Unwr Phase" avoids this behavior.

Flatness/Gain/Slope
Displays or hides trace parameters that the analyzer calculates for the selected evalua-
tion range ("Evaluation Range...").
Suppose that A and B denote the trace points at the beginning and at the end of the
evaluation range, respectively.
●
"Gain" is the larger of the two stimulus values of points A and B.
●
"Slope" is the difference of the stimulus values of point B minus point A.
●
"Flatness" is a measure of the deviation of the trace in the evaluation range from
linearity. The analyzer calculates the difference trace between the active trace and
the straight line between points A and B. The flatness is the difference between the
largest and the smallest response value of this difference trace.
Remote command:
CALCulate<Chn>:STATistics:SFLatness[:STATe]

Evaluation Range Dialog
The "Evaluation Range" dialog defines the range for the "Trace Statistics" and certain
marker search results ("Multiple Peak" and "Bandfilter" search). The evaluation range
is a continuous interval of the sweep variable.
