The IEC 61000-4-3 standard specifies the details about the radiated immunity test. The purpose of this test is to verify the EUT immunity to electromagnetic radiation that are generated by radio transmitters, cellular phones, and other industrial electromagnetic sources. The test is performed in an anechoic chamber and the EUT is placed on a non-conductive table at 0.8-m height. The test distance between the EUT and the antenna is 3 m. The EUT is exposed and tested in the field of horizontal and vertical polarity at each rating. The RF test signal is swept from 80 MHz to 1 GHz, and from 1 GHz to 2.7 GHz with a disturbance signal of 80% amplitude modulated with a 1-kHz sinusoidal signal. The field strength is 10 V/m and 18 V/m for each frequency range. The conversion data is captured from the EUT by the PHI controller card and sent to the laptop running the software script outside the chamber through the fully isolated optical fiber cables.
