Data concerning the size and speed of the high- and low-speed scanners are followed by a description of the motors and the electrical equipment necessary to drive these. The maximum rate of change of frequency that can be followed by the high-speed scanner is mentioned and a method of testing the rate of change of frequency of the transmitter synchronizing pulses is described.
