Abstract
This paper deals briefly with (1) the desirable characteristics of measuring equipment employed in making the usual tests of radio receiver performance and (2) a description of apparatus and technique used in carrying out several special tests. Measuring equipment and methods are discussed with reference to the elements of the receiver, after which are remarks on the usual tests of sensitivity, selectivity, and fidelity. Under special tests is a discussion of measurements on hum, tube and circuit noise, modulation distortion, intermodulation, audio harmonic analysis, and volume control. Some specimen curves showing results obtained on model receivers are presented.
