Abstract(in English) | In the frequency range below 30MHz, radio disturbances generated by an EUT are measured with a LAS consisting of three large loop antennas of about 2m or more in diameter. The LAS characteristics and the influences of EUT size, EUT setup, and connected line layout are theoretically investigated by numerical simulation using NEC2 and FEKO. It is found that, for achieving a measurement reproducibility within +/-3dB, the size of an EUT (magnetic source) is limited to less than 1m in dia. On the other hand, the LAS measurement is difficult to apply to an EUT of electric source, because measurement results greatly vary (more than 15 dB) with the EUT position even in an area of 1m dia. The imbalance current flowing on the EUT power line and/or signal lines extended outside the LAS are found to cause considerable influences to the LAS measurement. |
