適用范圍：This part of IEC 60244 details a measurement method for external intermodulation products (intermodulation components) caused by two or more transmitters using the same or adjacent antennas. It describes recommended methods of assessing the performance of radio broadcast transmitters. The purpose of the measurements described in clauses 4 and 5 of this part is to prove, as far as possible, that the requirements of the Radio Regulations with respect to maximum permissible radiated levels of intermodulation products from LF, MF, HF, VHF, UHF and SHF transmitters will be fulfilled when two or more transmitters use the same or nearby antennas. The method of measurement given in this part is not appropriate for type tests and IT SHOULD BE NOTED THAT THE MEASUREMENTS ARE TO BE CARRIED OUT ONLY WHEN MUTUALLY AGREED between the purchaser and supplier of the equipment.
