FIELD: physics, measurement technology.
SUBSTANCE: invention relates to measurement techniques and can be used to measure electric field intensity of the atmosphere when conducting weather, geophysical and radiophysical studies, as well as for evaluating the environmental state of the atmosphere and the surface of the Earth, particularly when investigating natural and man-made electromagnetic backgrounds of the earth's atmosphere. The device comprises a receiving antenna, connected to the common point of oppositely connected varicaps, the anodes of which are connected to the secondary coil of a transformer, the primary coil of which is connected to a modulating voltage generator, and a recording system. The device also includes a controlled EMF source, the input of which is connected to the output of the recording system, the output is connected to the middle point of the secondary transformer coil, wherein the input of the recording system is connected to the receiving antenna through a band-pass amplifier.
EFFECT: invention widens the width of the dynamic range of the device for measuring electric field intensity.
