opens a dialog to define the range for the statistical and phase evaluation.
Statistical Evaluation
The
Min/Max/Pk-Pk
,
Mean/Std Dev
, and
RMS
commands in the
Trace Statistics
submenu display or hide
the maximum
(Max)
, minimum
(Min),
the peak-to-peak value
(Pk-Pk),
arithmetic mean value
(Mean)
, the
standard deviation
(Std Dev)
, and
the
RMS
value of all response values of the trace in the selected
evaluation range
(Eval Range...).
Open the
Nwa-Setup
dialog and open the
System Configuration
dialog to toggle between non-
transparent and transparent info fields.
Definition of statistical quantities
The statistical quantities are calculated from all response values in the selected evaluation range.
Suppose that the trace in the evaluation range contains n stimulus values x
i
and n corresponding
response values y
i
(measurement points).
•
Mean
is the arithmetic mean value of all response values:
•
Std. Deviation
is the standard deviation of all response values:
•
Max.
and
Min.
are the largest and the smallest of all response values y
i
.
•
RMS is the root mean square (effective value) of all response values:
•
P-P
is the peak-to-peak value and is equal to the difference
Max. – Min.
The definitions given above apply to all linear, scalar trace formats. For a dB Mag trace, the Mean,
Std. Dev. and RMS are calculated before logarithmation.

Phase Delay/El. Length
Displays or hides the phase delay
(Phs Dly)
and the electrical length
(El Len)
of the trace in the selected
evaluation range
(Eval Range...)
. The parameters are only available for trace formats that contain phase
information, i.e. for the formats
Phase, Unwrapped Phase
, and the polar diagram formats
