Abstract
THE POLAR vector indicator is a device to indicate the magnitude and relative phase angle of two or three voltages as vectors on a cathode-ray tube screen. A reference voltage is chosen and assigned the arbitrary angle of zero degrees. It is shown as a straight horizontal line whose half length, starting at the center of the cathode-ray screen and extending to the right, is proportional to the amplitude of the reference.
