FIELD: physics; technology of manufacturing.
SUBSTANCE: invention relates to automatic control over a quartz generator operation and can be used at frequency hopping for switching over quartz generators in various equipment. Automatic control over quality of quartz generators operation is provided by availability of the first and the second quartz generators with two quartz resonators in each, a diode, an automatic control circuit with relay contacts, a power supply source and a load.
EFFECT: absence of retuning into a false generation frequency, suppression of higher harmonics of the signal frequency at the output of the quartz generator, duplication of the quartz generator at termination its generation or at the generation frequency hopping.
