In addition, in the case of television broadcast receivers, there may be radiation of power from other sources beside the local oscillator. In this standard the potential sources of spurious radiation from frequency modulation and television broadcast receivers are described and methods of measurement whereby the strength of some of these radiations may be determined are set up. Where the methods for the two classes of receivers differ, the specifications for each are outlined.187-1951 - IEEE Standards on Radio ReceiversIEEE Std 187-1951: IEEE Standard on Radio Receivers: Open Field Method of Measurement of Spurious Radiation From Frequency Modulation and Television Broadcast ReceiversRadio frequency modulationReceivers and receptionRadio frequency modulationReceivers and reception.621.3841361NjHacINjHaclDOCUMENT996280688603316IEEE Std 187-19512576304UNISA
