Methods of measurement for radio equipment used in the mobile services - Part 4: Transmitters employing single-sideband emissions (R3E, H3E or J3E) 移动业务中使用的无线电设备的测量方法 - 第4部分:采用单边带辐射的发射机(r3e H3e或J3e)
发布日期: 1991-07-10
涵盖了用于确定音频带宽通常不超过10 kHz的发射机性能的定义、条件和测量方法,该发射机用于传输语音和其他类型的信号,使用带全载波、减载波或抑制载波的单边带振幅调制。本标准拟与IEC 60489-1一起使用。
Covers the definitions, the conditions and the methods of measurement used to ascertain the performance of transmitters having audio-frequency bandwidths generally not exceeding 10 kHz for the transmission of voice and other types of signals, using single-sideband amplitude modulation with full, reduced or suppressed carrier. This standard is intended to be used in conjunction with IEC 60489-1.
