Assume that the result at a sweep point is given by the complex quantity z = x + jy.
Then the magnitude of z is calculated as
|z| = sqrt(x
2
+ y
2
)
and in phase notation we have
z = |z| e j Phase(z) , where Phase(z) = arctan(y/x).
The meaning of the parameters is as follows (see also table in

description):
MLINear Displays |z| in a Cartesian diagram
MLOGarithmic
MAGNitude (for compatibility with R&S ZVR ana-
lyzers)
Calculates |z| in dB (= 20 log|z|) and displays it in a
Cartesian diagram
PHASe Calculates Phase(z) in the range between -180° and
+180° and displays it in a Cartesian diagram
UPHase Calculates Phase(z) (unwrapped) and displays it in
a Cartesian diagram
POLar
COMPlex (for compatibility with R&S ZVR ana-
lyzers)
Displays z in a polar diagram
SMITh Displays z in a Smith diagram
ISMith Displays z in an inverted Smith diagram
GDELay For frequency sweeps only
Calculates the group delay at the related sweep
point and displays it in a Cartesian diagram
REAL Calculates Re(z) = x and displays it in a Cartesian
diagram
IMAGinary Calculates Im(z) = y and displays it in a Cartesian
diagram
SWR Calculates the standing wave ratio (1 + |z|) / (1 - |z|)
and displays it in a Cartesian diagram
LOGarithmic Displays z in a Cartesian diagram with logarithmic
scale
