(Revision of IEEE Std 187-1990) Abstract: Spurious radiation from sound and television broadcast receivers of the superheterodyne type are possible sources of interference with other radio services. This standard describes the potential sources of spurious radiation from receivers intended for the reception of sound and television broadcast, and the measurement methods for them.

To add new Advanced Televsion System Committee (ATSC) television standards to the present standards and clarify areas in conflict with current US Federal Communication Commission (FCC) requirements. This will include investigation of new TV recievers already being sold in the USA, including National Televsion System Committee (NTSC), ATSC and Digital Satellite System (DSS) and various combinations of these transmission methods. Finally, to expand the current standard which only applies to Table Top TV measurement setups, to include Set Top Box (STB) recievers and Rear Projection TV receivers.

This standard is needed to assure common measurement procedures for RF emissions in present and new technology products during the transition of NTSC analog TV to ATSC and DSS digital TV products in the USA and to ensure FCC accepts this industry need.
