Radiated Immunity Test Equipment

Radiated immunity testing involves subjecting the equipment under test (EUT) to strong radiated electromagnetic fields. Real world electromagnetic disturbance sources come from a wide range of sources, including cell phones and motors to name a few. The EUT must continue to operate normally and cannot show any signs of susceptibility when subjected to these electromagnetic fields. The electromagnetic fields are generated by feeding a calibrated signal into a broadband RF power amplifier. The output of the amplifier is then connected to an antenna which produces the radiated electric field. 

Radiated immunity test systems can be setup in a conventional way with many separate instruments or in a more convenient way with a control unit. The control unit consists of a signal generator, directional coupler, RF power meter and relay switching unit. RF power amplifiers, antennas, RF field strength meters, RF cables and control software complete the test equipment setup.
