of the data, measured in degrees. This format displays the phase shift versus
frequency.

menu. Adds or subtracts a phase offset that is constant
with frequency (rather than linear).
Softkey
in more format menu. Displays a polar format. Each point on the
polar format corresponds to a particular
value
of both magnitude and phase.
Quantities are read vectorally: the magnitude at any point is determined by
its displacement from the center (which has zero value), and the phase by
the angle counterclockwise from the positive x-axis. Magnitude is scaled in a
linear fashion, with the value of the outer circle usually set to a ratio value of
1. Since there is no frequency axis, frequency information is read from the
markers.
Softkey
in more cal menu. Allows compensation of phase shift due to an
extended measurement reference plane.
See “Port Extensions” in Chapter 5 for more information.
