Polar Format

softkey displays a polar format as shown in

7-10. 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.
