This standard is intended to specify the conditions and methods of measurement to be used to determine the characteristics of a radio receiver, so as to make possible the comparison of results of measurements made by different observers. Limiting values of the various quantities for acceptable performance are not specified. It constitutes a cataloque of selected measurements, recommended for assessing the essential properties of radio receivers. The methods of measurement are generally conceived to permit analyzing the overall performance of the receiver, considered as a quadripole (two-port) without any attempt to study its elements separately. However, depending on the characteristics to be measured and the type of receiver, it may be practicable, for experimental simplification, to carry out measurements on parts of the receiver by injection or extraction of signals at appropriate places in its circuits.
