Description / Abstract: Present-day radio receivers vary so greatly in their manner of operation that it is difficult to set down a single test procedure for each fundamental characteristic and have the procedure include all the allowances that should be made for the peculiarities of different sets. It is simpler to describe in general the test assemblies and adjustments of input and output, the operating conditions, and the radio receiver adjustments as a p plied to any type of receiver. Then recommended procedures for measuring sensitivity, selectivity, and fidelity, and other characteristics, can be outlined.
