What are E-Field Generators?
Electric Field Generators are used to convert RF Power into Electromagnetic Field or E-Field. This is most often used during EMC Testing where a Power Amplifier is connected to an E-Field Generator to generate an E-Field that can be used for EMC Immision Testing.
E-Field Generators are coils of electric conductors, normally copper wire, that are tightly wound onto a metal core and are mounted to turn around inside an exhibit of large magnets. An electric conductor moves through a magnetic field, the magnetism will interface with the electrons in the conductor to induce a flow of electrical current inside it. The conductor coil and its core are called the armature, connecting the armature to the shaft of a mechanical power source.
These generators work on the principle of faraday's law of electromagnetic induction. Faraday's law states that whenever a conductor is placed in a varying magnetic field, EMF is induced and this induced EMF is equal to the rate of change of flux linkages. This EMF can be generated when there is either relative space or relative time variation between the conductor and the magnetic field.
The device under the test is subjected to this generated field and the parameters of the device are calculated as per EMC norms. It is specially designed for the EMC immunity test for RF devices and can easily be successively tested in both polarizations with/without being dismounted.
everything RF has listed E-Field Generators that can be used for EMC testing from the leading manufacturers. The list of E-Field Generators can be narrowed down by various parameters.
