This section deals with baseband-to-baseband measurements of the noise performance of simulated radio-relay systems used for frequency division multiplex (f.d.m.) telephony. These measurements are signal-related and are additional to those already given in Part 3, Section Two of this publication, Measurements in the Baseband, which are common to telephony, television and sound programme transmission.

The methods of measurement described in the following sections of this part apply to subsystems including those which are not part of a simulated system (e.g. antennas). The methods are intended to cover those electrical characteristics which influence the performance of radio-relay systems and should be used in conjunction with Part 1 of this publication: Measurements Common to Sub-systems and Simulated Radio-relay Systems. Values for the various quantities to be measured are not specified since these should be given in the detailed equipment specification.

This standard gives methods for measuring the figure of merit (GIT) of earth station receiving systems operating in the 4 GHz to 6 GHz range. One method, using stars having known flux densities at the site of the earth station, takes into account the error caused by various parameters. An indirect method is also given.

This technical report contains the requirements necessary for the safety of personnel against hazards which may occur in operating and maintaining mobile radio equipment. Where mandatory requirements exist relating to safety, these take precedence over the requirements given in this report. This report applies to all mobile radio equipment and auxiliary apparatus, including combining units and matching networks, antenna systems and associated feeder-lines.Remote controls and private or public telephone interconnect circuits are also included.This report refers to all classes of protective insulation and equipment defined in IEC 536. NOTE — Power supplies and battery chargers operating outside the housing of the mobile or fixed radio installation are not included in this scope. This report deals with protection against: - injury; - electric shock; - skin burns; - high temperature and fire; - harmful radiation; miscellaneous hazards. Design and construction requirements and, where appropriate, test methods are specified covering: a) the safety of personnel when operating, carrying out routine adjustments to, and as far as practicable, during fault finding and repair of the equipment; b) the safety of personnel when the equipment is operating normally and also when it is operating under certain specific fault conditions which may arise in normal use; and c) the prevention of fire and its spread. The requirements do not necessarily ensure the safety of personnel working on the equipment when it is not in normal operation. Tests are specified, where appropriate, for checking that the equipment meets the safety requirements of this report when operating normally and also under the specified fault conditions. These tests should be carried out on a representative set of equipment in order to determine whether the design meets the requirements of the report. The use of this report is not, however, intended to be restricted to type tests. It may also be used for acceptance tests after installation of the equipment, for tests after modifications to parts of the equipment and for tests at appropriate intervals to ensure the continuing safety of the equipment throughout its life.

Methods are given in this section for the measurement of the electrical characteristics of frequency demodulators. Threshold aspects are not included as these are not normally required for line-of-sight radio-relay systems. Furthermore, where possible, only measurements involving the basic demodulator are considered, excluding the equipment comprising the de-emphasis network and the networks associated with sound sub-carrier signals, pilot signals and auxiliary signals. Methods of measurement for frequency modulators are given in Section Four. Measurements between the baseband terminals of modulator/demodulator assemblies are covered by various sections of Part 3 of this publication.

Methods are given in this section for the measurement of the electrical characteristics of frequency modulators. Furthermore, where possible, only measurements involving the basic modulator are considered, that is excluding the baseband section comprising the pre-emphasis network and the networks associated with sound sub-carrier signals, pilot signals and auxiliary signals. Methods of measurement for frequency demodulators are given in Section Five. Measurements between baseband terminals of modulator/demodulator assemblies are covered by various sections of Part 3 of this publication.
