适用范围

This part of IEC 60489 refers specifically to mobile radio transmitters and receivers for the transmission of data (telegraphy) signals having the emission characteristics given in 1.1. This standard is intended to be used in conjunction with IEC 60489-1. The terms and definitions and the conditions of measurement set forth in this standard are intended for type and acceptance tests. The object of this standard is to standardize the definitions, the conditions and the methods of measurement used to ascertain the radio-frequency performance of data and selective call equipment, thus making possible meaningful comparisons of the results of measurements made by different observers and on different equipment. This standard will cover the following types of data signals: - bit streams; - character strings; - messages; - selective calling. Selective calling differs from messages in their intended functions; it may be considered as data signals, analogous to messages transmitting only the information required to activate an alarm on one receiver or a group of receivers. The methods of measurements for the radio-frequency parameters are appropriate for the four types of data signals. To differentiate between the radio-frequency parameters (e.g. adjacent channel power, frequency error) measured in this standard from those in associated standards, the name of each parameter is followed by either "(bit stream)" or "(character string)" or "(message)" or "(selective calling)". After each radio-frequency parameter the general term "(data)" is used. When each equipment is measured, the proper data type "(bit stream)" "(character string)" "(message)" or "(selective calling)" will be substituted for "(data)".
