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 reaUmaginary marker are available in the polar marker menu.
