A parametric oscillator with an effective protection against interference comprises a ferromagnetic core with non-collinear magnetic fields, input, output windings orthogonally arranged in the windows of a magnetic core, and a condenser in series connected with a circuit (output) windings. The device is additionally equipped with a winding for induction level control produced by a pumping winding, a key series circuit of a relay stabilizer comprising a zener diode by its anode connected to one terminal of the winding for induction level control of the pumping winding, to the second terminal of this winding one output of the relay for control of predetermined induction is connected, which by its other terminal is connected to cathode of a zener diode; a linear inductance, which is in series connected to one terminal of the pumping winding and having a section of winding turns, which is switched by front and back contacts of the relay for control of the level of induction of pumping winding, which are bridged by two dynistors connected in opposite-parallel manner. |
