Annotation
This is the second volume of the two-volume documentation of the Personal FM Transceivers testing program results.
Abstract
This volume of the program presents the test data of the program. It contains a lengthy compilation of the test results upon which the contents of the first volume (containing a summary of the program report) are based. The highly technical material is introduced by an explanation of the testing methodology. The Federal standard used to measure the equipment is also explained. The bulk of the volume contains tabular data of the testing results. Initial tables display a general summary of the transceiver test data grouping the transceivers into types and indicating only that a transceiver was or was not in compliance with the minimum performance requirements of the standard. The results are shown for tests under both ambient temperature test conditions and tests under conditions of environmental extremes for the 26 transceiver characteristics tested. Complete test data, the basis of the summary tables, are presented in the appendix.
