Abstract

Describes the conditions and methods to measure unwanted radiations originating from sources other than the aerial or aerial system of radio transmitters. The standard is intended to be used in conjunction with Publication 244-1. The methods of measurement described in this standard are intended for type tests but they may also be used for acceptance tests and factory tests. Does not apply to transmitters in which the aerial cannot be disconnected or disabled and replaced by a test load.
