National (State Primary) Standard of electromagnetic field strength in the frequency range from 0.01 MHz to 43 GHz
The standard of electromagnetic field strength is created for research of electromagnetic emission, tests on electromagnetic compatibility, calibration of E-Field meters and antennas.
The standard consists of two parts: a GTEM camera (range 0.01-1000 MHz), and a anechoic chamber (range 1000-43000 MHz). The magnetic field strength is formed at a certain point inside one of the chambers, by means of a radiating antenna. The required power high-frequency signal is fed to the antenna.
