Sound and Television Broadcasting Receivers and Associated Equipment - Limits and Methods of Measurement of Immunity Characteristics
This Standard establishes limits and methods of measurement of the immunity of radio and television broadcasting receivers and certain associated equipment to degradation of performance due to electromagnetic disturbances.
This Standard is applicable to immunity of two classes of equipment from degradation of performance resulting from voltages and currents which are caused by electromagnetic disturbances, and which are induced within the equipment or in the external connecting cables associated with it; provided that the equipment is operated at the supply voltage, and in other respects in the manner specified by the manufacturer.
The two classes of equipment are
(a) all equipment designed for the reception of broadcast television or radio signals, and equipment designed for use with, and connection to, such broadcasting receivers, including but not limited to, video recorders, cable television converters, tape and record players and audio processing devices;
(b) equipment designed for the reproduction or amplification of audio signals from tapes or records and similar devices not intended for connection to broadcasting receiving apparatus.
This standard does not apply to interface equipment attached to the public switched telephone network.
INTERNAL IMMUNITY OF RADIO RECEIVERS IS NOT WITHIN THE SCOPE OF THIS STANDARD EXCEPT IN THOSE CASES WHERE ITS MEASUREMENT CANNOT BE ISOLATED FROM THE MEASUREMENT OF EXTERNAL IMMUNITY. (See Appendix A.)
1.3 Frequency Range
This Standard applies to electromagnetic disturbances having components in the frequency range from 0.15 to 1000 MHz.
