Testes em equipamentos de comunicações que operam nas faixas de HF, VHF e UHF, em radiotelefonia, com modulação de frequência.

Abstract

This work deals with the test conditions, instruments and methods for measuring the electrical characteristics of FM receivers and transmitters operating between 25 MHz and 1GHz, and also addresses the minimum specifications of each test established by institutions that regulate or recommend reception test standards and transmission in several countries. In the measurement methods presented, the equipment under test is considered as quadripoles, analyzing its general characteristics, without, however, studying the parts, components and circuits that constitute them.
