Abstract
This paper reviews current developments in the measurement of the immunity of receivers for sound radio and television broadcast reception from high-level ambient radio-frequency fields.The need for the control of immunity is justified by quoting examples of field strengths generated by authorized transmitters in which sound radio and domestic television installations are required to operate satisfactorily.The main attributes of standard methods of measurement, which may be adopted internationally are listed. The principal methods which are at present being considered are described and compared.It is shown that each has its limitations, but that by careful selection it is possible to conduct immunity measurements simply and with confidence over the frequency range 10 kHz to 1 GHz.
