SETUP FOR GENERATING AN ELECTROMAGNETIC BACKGROUND

The utility model relates to the field of radio electronics and can be advantageously used for the generation of electromagnetic radiation of radio spectrum in order to form a stable low intensity electromagnetic fields on testing using bioelectrography or otherwise discharge visualization. The device includes a power supply (1) connected in series the charge resistor (2), storage capacitor (5) and transmitter antenna (6) connected to a power supply (1), a key-based semiconductor device switching circuit which is connected to provide a parallel connection of the storage capacitor (5) and the radiating antenna (6) with open key, the master oscillator (11) connected to the control input of the key, characterized in that it is provided with a voltage stabilizer parametric charge capacitor, shunt diode (7) and limiting resistor (8) connected in series and connected in parallel to the radiating antenna (6), and the radiating antenna (6) is in the form of a conductor frame. One of the important distinguishing features is a pulse shaper based on key management (triac) through a programmable generator which allows to vary the pulse repetition frequency of the exciting antenna circuit and control power (intensity) the radiation, and consequently, a tense of the electromagnetic field produced by the device.
