Polar Format
The POLAR, softkey displays a polar format as shown in Figure 5-9 on page 5-17. 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. The default marker readout for the polar format is in linear
magnitude and phase. A log magnitude marker and a real/imaginary marker are available in the polar
marker menu.
