Abstract

PURPOSE:To control the oscillation frequency in a short time, by controlling the oscillation frequency by feedback after the mechanical position of the tuning mechanism of a magnetron is matched to an instructed position approximately. CONSTITUTION:One of voltages of a reference voltage generating circuit 2 is selected by the command of a frequency channel selecting circuit 1 and is compared with a voltage, which is obtained by converting the angle position of a tuning mechanism 3 by a converting circuit 5, by an angle error detecting circuit 6. The output error signal is applied to the tuning mechanism 3 through a switch circuit 7 and a mechanism driving part 8 to correct the angle position. When the error signal becomes smaller, the switch circuit 7 is switched by the output of a convergence discriminating circuit 12, and an error signal obtained by comparing the output of a local oscillator group 9 selected by the selecting circuit 1 with the oscillation frequency of a magnetron 4 by a discriminating circuit 11 is applied to the mechanism driving part 8. Thus, the oscillation frequency is controlled precisely.
