3.2.4.6 Measured Quantities and Display Formats
The analyzer allows any combination of a display format and a measured quantity. The
following rules can help to avoid inappropriate formats and find the format that is ide-
ally suited to the measurement task.
●
All formats are suitable for the analysis of reflection coefficients S
ii
. The formats
"SWR", "Smith" and "Inverted Smith" lose their original meaning (standing wave
ratio, normalized impedance or admittance) if they are used for transmission S-
parameters, ratios and other quantities.
●
The complex "Impedances", "Admittances", "Z-parameters", and "Y-parameters"
are generally displayed in one of the Cartesian diagrams with linear vertical axis
scale or in a polar diagram.
●
The real "Stability Factors", "DC Inputs", and the "PAE" is generally displayed in a
linear Cartesian diagram ("Lin Mag" or "Real"). In complex formats, real numbers
represent complex numbers with zero imaginary part.
The following table gives an overview of recommended display formats.
Complex dimensionless quan-
tities:
S-parameters and ratios
Complex quantities with dimensions:
Wave quantities, Z-parameters, Y-
parameters, impedances, admittan-
ces
Real quantities:

eters, impedances, admittances)

changed.
3.3 Measured Quantities
This section gives an overview of the measurement results of the network analyzer and
the meaning of the different measured quantities. All quantities can be selected in the
"Trace – Meas" submenu.
