Abstract : The article discusses frequency stabilization systems, noting that one advantage of using a pulsed phase analyzer to control the oscillator is that the frequency of the standard signal need not be tuned to that of the oscillator. The system will operate in the synchronized state when the frequency of the oscillator consists of integral multiples of the standard frequency. The synchronization limit far exceeds the unstable synchronization limit. The characteristics of the auxiliary wave are shown experimentally to be good. Both the synchronization band and the capture band exceed normal requirements. Since a large number of tubes are used, the voltage regulation requirement is stringent. Between pulses, there is no output of error-correcting voltage from the phase analyzer; hence the system cannot correct instantaneous frequency drift. In the future, it is desirable to increase the density of the noncontinuous frequency spectrum as well as to increase the frequency of the controlled oscillator by means of the millimicrosecond pulsing technique.
