Abstract

PURPOSE:To make stable the oscillation frequency of sweep generator, by the phase synchronization of an aribitrary oscillation frequency in the sweep frequency of the sweep oscillator of voltage control type to the frequency of high stabilization such as crystal oscillator. CONSTITUTION:The phase synchronization loop consists of the voltage controlled sweep oscillator 1, amplifier 2, divider 4, phase comparison circuit 6, LPF7, and adder 8. When the oscillator 1 is swept with the saw tooth waves of sweep period t, the frequency is swept from f1-f2 and the frequency is f1 and is constant at the next blank period (repetitive period T-sweep time t). Phase synchronization is made at the oscillation frequency range narrower in the capture range at the blank period, and at the sweep period t, sweeping is made from the frequency f1 in phase synchronization by the band width given at the sweep control circuit 12. The frequency of leading of sweep signal is made stable with the reference oscillator 5 made of highly stable crystal oscillator.
