IRE Standards on Radio Receivers:Method of Testing receivers Employing Ferrite Core Loop Antennas, 1955

The technique for introduction of a test signal into a loop antenna (see Standards on Radio Receivers--Methods of Testing Amplitude-Modulation Broadcast Receivers--1948, Section 4.01.03, for example) has long been employed with receivers using aircore loop antennas. These antennas are normally of a more or less flat or pancake construction and, in general, lend themselves to the method described in the standard without ambiguity. When this method is extended to loop antennas wound on cores of high permeability in which the length-to-diameter ratio is high, it tends to break down. When the test loop and this type of antenna are coaxial, it is usually not feasible to assign a spacing between these two for calibration purposes. Moreover, the use of the induction field to simulate the actual radiation field received by the loop is a satisfactory procedure only if the loop is immersed in a reasonably uniform field. This is substantially the situation with flat air core loops using the aforementioned technique but is not approximated satisfactorily when the relatively long ferrite core loop antenna is employed. This present standard describes a modification of the existing techniques which allows for the measurement of a receiver employing a ferritecore loop antenna with the same precision as that obtained in the measurement of air-core loop antennas

No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
