  • IEC 60315-1-1988 - 中外标准 - - 1988/12 - 现行
    Applies to radio receivers of any kind excluding television receivers, and to the parts of which they are composed, or which are used as auxiliaries to such receivers. Deals with the determination of performance, the comparison of equipment and the determination of proper practical applications by listing the characteristics useful for specifications and laying down uniform methods of measurement for these characteristics. Also replaces IEC 60315-2 (1971). The contents of the corrigendum of July 1997 have been included in this copy.

    GB/T 10198.3-1988 - 中外标准 - - 1988/12 - 现行
    为了使三类文件传真机能通过电话线路在1 min左右时间传送一张GB 148《印刷、书写级绘图用纸幅画尺寸》所规定的A(4)幅面的文件。考虑到大多数应用来说,黑白复制是足够的。为要求文件传真通信能与电话交替接通,当双方设备有一方或双方是自动的情况下亦能接通;在这两种情况下,其操作程序应按《在公用电话交换网中进行文件传真通信的程序》(CCITT T.30建议书)的规定进行。本标准规定了用于公用电话交换网和租用线路上的三类文件传真机的设计和操作。本标准等同采用国际电报咨询委员会建议书CCITT T.4(1980)《文件传真三类机的标准化》。

  • IEC 60489-3-1988 - 中外标准 - - 1988/12 - 现行
    Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using angle modulation (phase/frequency modulation), or double-sideband amplitude modulation with full carrier. This standard is intended to be used in conjunction with IEC 60489-1.
